Plot hole: Freddy is killed at the end because he sees his own reflection in a mirror, which causes the souls in his body to revolt and kill him. But this weakness to mirrors and reflections doesn't fit in any other film of the series. He repeatedly appears in mirrors in the other films, and in the climax of "Dream Warriors," he even appears in a hallway of mirrors that are facing each other, where he would have seen his own reflection multiple times. No matter how you slice it, his death in this movie doesn't add up in the overall context of the series.
Plot hole: While Harrison Ford is taking a shower shortly after arriving at the hotel, the 'bad guys' kidnap his wife from the hotel room. How did they know she was the one who had picked up the wrong suitcase (which contains what they are after) at the airport? They could only have assumed that. And the suitcase they were after was in the room so why didn't they just take it?
Suggested correction: Ford himself explains how they know she picked up the wrong suitcase. Emmanuelle Seigneur grabs Ford's wife's suitcase by mistake, and puts it in the locker to be collected by the bad guys. The bad guys then go to the locker and get the suitcase - only to discover it's the wrong one. Ford specifically mentions her name and address tag is on her bag, so they see that, and immediately know who to look for.
But, why did they have to kidnap her? They could just take the suitcase and leave her alone. They came all the way to her room but not looking for the suitcase?
Good point, but that still doesn't explain why they simply didn't take the case from the hotel room instead of kidnapping Mrs Walker and holding her ransom for it. Suggested answer - they wouldn't have been able to make a movie out of it.
Plot hole: Three gunshots were fired for Kurt and Ram's "double suicide" and almost two minutes pass between shots 2 and 3. Doubtful two police officers could think they shot each other.
Suggested correction: An officer could think that one boy shot the other twice, killing him with the second bullet, before that boy was successful in killing him. The remaining boy would then kill himself. "Shot each other" might be a sloppy description, but basically, Kurt and Ram are both dead. There is a letter - forged by Veronica - which "reveals" that they were a couple. No signs of anyone else being involved. The police consider it a "double suicide" because they believe the letter.
Interesting theory, but I respectfully disagree with your correction. Three gunshots to two dead bodies, each with one bullet wound, would arouse suspicion despite what a letter found at the scene says. If one of the boys killed himself, there would be some evidence to support that such as powder burns around the wound or powder residue on his hands. In fact, a forensic scientist would have performed a GSR test on the hands of the shooters to confirm they did in fact fire the weapons.
Plot hole: The movie at best is being dishonest with the ending of the chase scene; to keep Dr. King as a possible suspect, the gunshot happens so shortly after she went out of frame (with no cuts) that (since she is -NOT - the killer) there is no possible way that the gun could have ended in her hand. There's also no possible way for the culprit to escape, to find Hassan in the crowd and be there at the perfect moment, etc. (01:16:35)
Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.
