Plot hole: The killer shows up at the scheduled appointment at 8 AM. They kill the idiot blackmailer with an overdose of morphine. Remember, that morphine that supposedly killed Thrombey in 10 minutes. Marta finds the blackmailer at 10 AM...alive, and does CPR on them, keeping them alive long enough for the ambulance to come and bring them to the hospital, even if in critical condition. So we went from "kills in 10 minutes, you can't even try to save him" to "after 2 hours, you are still hanging on"? (01:56:10)

Suggested correction: Marta injected an absurdly large dose. A smaller overdose would not kill in 10 minutes.
I read that objection before. From 10 minutes to 2 hours there's quite a leap that the movie does not explain or address at all, if it were part of the plot they should have said why this difference, on something so time sensitive (of which they got the factual details wrong anyway). Even visually when you look at the dose injected to Harlan and the dose in the syringe for the murder, they do not look different. He even stabs her with the syringe. Which makes sense since he has no reason to leave her there with a small. Controlled overdose in her veins risking that she would be saved as it -almost - happens - it's amazing he got away with it to begin with because she is so dumb to show up for no reason in a derelict place without talking to her accomplice that passed her the toxi report, or anyone.Without a throwaway line from an investigator or anything of the sort ("but you injected her the wrong way, so she was still alive two hours after"), we are just left with an inconsistency.
Suggested correction: You've assumed a hell of a lot! Marta said Thrombey was given a dose of 100 mg (instead 3) of Morphine and would die in 10 minutes unless given the antidote. You just asserted that "Thrombey would die in 10 minutes" as if it was fait accompli, while Thrombey didn't die of morphine overdoes at all! (He cut his own throat.) For all we know, Marta's 10-minute assessment was a worst-case-scenario assessment. Fran's age and physique, as well as Marta's CPR, helped negate the effect until the ambulance arrives. If the medics administered the antidote, it could have prolonged Fran's life. Finally, 2 hours is the time after which the viewer is informed of Fran's death, not her actual death time. Most importantly, this happens in the medical world all the time: A person who is supposed to die after 3 days lives for 16 years. There are case-by-case explanations for each one, but they baffle the medical examiners at first.
Two hours is not my assumption or when the viewer is informed of her death; the killer gives the appointment to the victim at 8 AM and to Marta at 10 AM, so as I said, after 2 hours with 0 medical care on her she is still hanging on and with barely a little tap she is ready to dispense important clues. I go by what the movie says also about the 10 minutes overdose time. Of course if you tell me that baffling freak occurrences can happen all the time in medicine and that very precise statements from the movie don't matter because the character can just have gotten it wrong by over 10x and the movie does not acknowledge it at all, well, that's a very respectable opinion; mine is that fiction (a whodunnit, not a slasher flick with a killer surviving multiple gunshots and the like) is not reality and it should respond to higher standards than "I guess she was still alive somehow."
I re-watched the movie to verify that Fran was given an appointment at 8 AM. I discovered something new: The bottle that was injected to Fran contained only 5 mg of Morphine. That's 1/20th of what was "supposedly" given to Thrombey Sr. So, yeah, 10x is OK. In fact, 20x is OK.
No, no; it contains 5 mg of morphine PER ml, it's the concentration, not the total. Go back to the scene when Marta "messes up", the vials are the exact same as the one that Ransom injects (obviously, since they come from Marta's bag after all). It's new for you but I covered that already in the Factual Error about it. It's something that piles upon a previous mistake. She did not give him 100 mg of morphine because it would have emptied the vial (which is more than half full) and because a full vial of ketorlac would have killed Trombe regardless, at that concentration! The movie gets both the props and the medical facts wrong (100 mg of morphine does not even kill most patients, Harlan would have not died in 10 minutes especially since he takes safely big doses of toradol and morphine), but nothing - in the script - says that Marta or Ransom got basic medical facts wrong.
Okay! It seems mistake after mistake is piling up. Now, it appears Fran lived 4 hours, during 2 of which she was unattended. Plus, 100 mg of Morphine from a 5 mg/ml vial amounts to 20 ml of liquid. Well, now, everything you say makes sense... or at least most of the things. On the whole, I think it was a complicated situation.
Continuity mistake: There's a clear mix-up in editing during the car chase. Marta checks her phone twice for Blanc's calls as she tries to get away from the police. The first time the phone signals 9:36 AM, the second time 9:34 AM. (01:31:50)
Factual error: Opening the blank envelope, Marta finds the fragment of the toxicology report. It is signed "Office of the chief medical examiner, Norfolk County, Massachusetts." But then it writes also the address of said office, which is in Marlborough. Marlborough is also the city when Marta resides, and where the lawyers' letters we see come from. But Marlborough is also a city in the Middlesex county, not Norfolk. (01:28:25)
Trivia: K Callan, who plays Christopher Plummer's mother in this film, is actually six years younger than Plummer in real life.
Trivia: Michael Shannon has played Jaeden Martell's father twice on screen, in this movie and Midnight Special.
Trivia: At the end, Benoit Blanc says he noticed the blood on Marta's shoe the first time she stepped in front of him. Rewatching the sequence when they first meet, as he says "I've been doin' a little pokin'" he does indeed look down as he speaks and takes a fraction of a second pause, noticing the blood but continuing to talk as normal. (00:23:45)
Benoit Blanc: I suspect foul play. I have eliminated no suspects.
Question: How did blood drop reached Marta's shoes, even though it was too far from Christopher Plummer in the suicide scene? (00:53:50)
Answer: To add slightly to the other answer, evidently some of the blood in the scene had to be digitally removed for the film to secure a PG-13 rating, which explains why we don't see any actual spray/gush. But we are to assume that a drop managed to splash onto her shoe when he slit his throat.
Answer: The rationale is that blood can travel quite far from an artery and her shoe therefore got the droplet on it even from the doorway - however it does seem to me that the filmic portrayal is lacking, since you don't actually see any instance of spray. Rian Johnson' script says "Blood gushes." What we see in the scene is that it is trickling down his cut - a bit.
Question: In the flashbacks of Ransom storming out, it's different each time. The first time his Grandma speaks, the second time she's silent, and the third time she's holding cake, when she wasn't the other times. The flashbacks we see don't contradict each other, they're not really portrayed as coming from unreliable narrators, they're generally an honest portrayal of what happens, even when what they're telling the police isn't what we see happen. So why these minor, certainly deliberate, differences? Far as I'm aware it's the only time it happens too, not like there are lots of moments like this.
Chosen answer: She is holding cake all 3 times, actually, so the only difference is that the first time she speaks. It can be a case of unreliable narrator, but I'd write it down as a mistake (deliberate, probably, as the phrase is important for the plot and they didn't want to hammer it in), since as you said, the other times even when they tell things to the police in a different way from what happened, the details tend to stay consistent, except for parts that are obviously made up, such as who is putting down the birthday cake for Harlan Thrombey therefore appearing subservient and not as close (when Richard tells the story, it's Walt and his wife, when Walt tells the story it is Richard and his wife).
Answer: Each time, it is being described by a different person. Maybe not all heard her speak.
Question: How come Ransom did not realise that Marta had not given Harlan the morphine when he went back to the study room to switch the evidence?
Answer: She didn't drain either of the vials so unless he actually measured how much of each liquid there was to start with, he was unlikely to notice that the amounts weren't quite what would have expected. He knew enough to know that the switch could lead to a death, but he's not anal enough to note every tiny aspect of the situation to verify that nothing's gone wrong.
