Plot hole: As the first prisoner is being pulled towards the organ cutter, you see on the wall the exact shape of the body organs for the brain, lungs, heart, liver, stomach, kidneys and testicles/ovaries that serve as guides and a track for tiny saw blades to come out and cut into the person's body to harvest these organs. The problem is these are in a fixed position, which might work for some people. However people are different sizes, shapes, and heights and most wouldn't match up to these blade guides. So a good majority of the people they cut apart to harvest organs out of wouldn't even give them good ones as the blades would cut into the organs and ruin them. (00:25:20)
Plot hole: Cleveland never tells his friends where Cecilia lives. Yet Lester is somehow able to call Immigration & Customs Enforcement and direct them to Cecilia's house. (00:14:05 - 00:15:10)
Plot hole: In the pilot Jimmy finds out Lucy is pregnant while visiting her cell. In S2 E21 (Inside Probe) he finds out while taking to Lucy on the prison phone.
Plot hole: The bad guy somehow knows what is going to happen (via the sketches) even though the events haven't happened yet, like knowing Mrs Peel was going to show up at Pool's mansion in that catsuit and hat, and that the scenes were going to play out like the sketches.
Plot hole: Someone as careful and controlling as Timo would never force anyone into working for him, for exactly this reason.
Plot hole: Why would Danger Mouse go on the roller coaster at the end without seeing Greenback go on it first? Greenback went first in the ghost train. It also doesn't make sense that Danger Mouse would go on it when Penfold pretty much tells him flat out that it IS a trap.
Into the Mouth of Evil - S2-E23
Plot hole: While fleeing the guru's disciples through a narrow side street, Jackie gets cut off by the van driven by Dr. Jamba and associates, stun-sprayed in the face, and then loaded into the van. But with three brutish-looking guys being so close to their quarry, the real crooks can take the time for dragging Jackie around to the back door instead of loading him through the side doors?
Plot hole: Kings Boomer and Brady had to earn their king rings and the powers contained within, however, King Boz was just handed the ring, yet it kept its power.
Plot hole: In the pilot, it is established that the surface of anything/anyone made invisible by "quicksilver" is freezing. (Darien gets caught in the women's shower because the mist freezes on him. He freezes the beer mugs for the doctors.) But in later episodes, nobody notices him standing invisible - and freezing!? - next to them.
Plot hole: This was the first episode of the series and we see that the rangers are unable to figure out how to properly operate their zords; but in Origins Part 1 (which takes place prior to this) they have no issues with the zords at all.
The Marathon - S4-E3
Plot hole: Jason cheated in three different ways in order to beat Aurelius in The Marathon, and admitted it. So the bet that they made between them is null and void. But the last shot shows them living up to the terms, which includes Aurelius starting to eat his own shit (literally), so revolted that he's trembling. Apparently the writers really really wanted to include coprophagy. But who would eat faeces for a bet, if you can simply avoid it by reminding your opponent that he cheated? Or even better, many would say that cheating means losing automatically, so he's the one who should be eating his own shit.
Plot hole: Tim has the mike in his hand and steps repeatedly forwards to talk to Jill, the cord being long enough to allow him to do so. However once Jill leaves and he wants to go after her the mike knocks over the jar of mosquitoes. Up until then, there was no indication that the mike had been changed or moved but he never at the risk of knocking over the jar until then.
Farewell My Beloved Witch - S1-E3
Plot hole: Lupin was captured by chance, and he did not plan for that, nor he seemed to have previous knowledge of Stern's appearance, but he escapes regardless using a Mission Impossible-like perfect mask of him. He also somehow kept his own blazer, tie and shoes underneath the uniform and boots he stole and wore. (00:16:00)
Plot hole: The scheme to lead a blindfolded Max and 99 to what they think is the airport via an illusion room would not work the way they do it. Since the base is underground, there is no way that what they did to represent ascending to ground level that would make a person think they were above ground.
Plot hole: Dillon was quickly identified by the city sensors as having metal parts, thus classifying him as a threat to the city. Yet Tenaya, who is essentially a cyborg, tries out for the Green Ranger without setting off the same sensors.
Suggested correction: Tenaya wasn't caught because the guards assumed the equipment was faulty. It was giving positives all day because of all the sleeper agents we find out about later.
Plot hole: The Jupiter 2 crew is duplicated; however, the aliens had never seen Penny (or Judy I think). How can they be duplicated? The aliens don't have ability to know who were there, or they wouldn't have questioned Smith about the crew. Also, they do not know Smith and Will are hiding. So, they don't arm to have any special power to know beyond what they actually observe.
