Plot hole: If Minh knew about the Power Rangers, their identities and their history, it makes no sense that she would expect to morph without being specifically chosen to become the Yellow Ranger.
Suggested correction: The rebel teenager archetype. If I had a dime for every time a kid didn't listen I would be a billionaire. It's not a mistake.
It doesn't make sense at all that Minh would expect to morph just because she had a power coin in her possession; she had to have been told about how it works.
Pretend that morpher is a gun and she's a teenager in the real world. To say no teen would pick it up, disobey an adult, just try it themselves is a joke. She's a kid. Kids do stupid stuff and don't listen.
I'm sorry, but I disagree. We are talking about the daughter of a Power Ranger, not a typical teenager. Trini, being the type of person she was, would have explained how it works; it is highly unlikely that Minh would make such a careless choice.
She didn't discover her mom was a Power Ranger until after death. There was a whole scene where she walked in, and Billy and Zach accidentally revealed it to her. Also, itization. All she's done was make careless, impulsive choices.
Plot hole: When Quasimodo is revealed to the crowd during the Festival of Fools, someone identifies him as "the bell-ringer from Notre Dame." This is the first time Quasimodo has ever left the cathedral, so he shouldn't know that.
Plot hole: Mr. Cranston asks Denise to be the accompanist for the school's production of "Chicago". This is an error. In the year 2009, in which the film is set, this would be impossible since the licensing company which has the theatrical rights for "Chicago" restricts the show from being produced (even by amateur groups and schools) anywhere in the greater New York area while there is an open-ended production running on Broadway.
Plot hole: Why is that shark machine even there? The only reason it's there is to help the plot, and I don't see how it is of use to anyone in the corporate world. If the shark just ejects the fish it turns into fish heads out to sea, there is too much chance they will be ruined by carnivorous fish or weather before they are picked up. And fishing companies should know better.
Plot hole: At the very beginning, as the passenger ship is foundering in a powerful storm, the little boy places his kitten in a box and tucks the box inside his shirt just moments before he is cast into the churning sea. Sinking into the depths, the boy and other passengers are presently rescued by Captain Nemo's team of divers, who supply the drowning passengers with oxygen until they board the submarine Nautilus. Once aboard, the little boy opens his hidden box to reveal a wet but very much alive kitten that could not possibly have survived submersion for that length of time in a box that was not waterproof.
Plot hole: Gail and Katie talk in her shed about Guy's phone call. Katie says "I didn't lie about anything", which is a really odd non sequitur. All Gail said was "I just got off the phone with Guy Morgan. Your phone. He just loved that little demo you left him. I have underestimated you. It'd make me proud if I actually cared about you." Nothing about it prompts a response like that, except the plot point that Gail told Guy that Katie lied about it appropriating Bev's demo. But Katie does not know that fact at that point. (00:21:00)
Plot hole: Eagle catches and flies off with one of the cubs and Benji goes chasing after the eagle. After a bit of searching he spots what appears to be the missing cub but then Benji is chased by the nearby eagle before turning around to drive it off. But strangely Benji abandons looking for the fourth cub, as from this point forward we only see three cubs with him. This doesn't jive, as Benji has up to this point done everything to protect the cubs and keep all four of them together. (00:58:20 - 01:00:06)
Plot hole: In the beginning after Flint buries the treasure, he kills all the men that are with him. The pistols he has are one-shot pistols, so there's no way he could kill 14 men using only two one-shot pistols.
Plot hole: Since the criminals who used the dogs to rob the bank in the first movie were never apprehended (No criminal worth their salt would tell the authorities their caper was spoiled because the canines ran off with their loot), there is no way the people who are hunting the dobermans in the beginning of this movie would know the dogs were still carrying the cash. (00:18:00)
Plot hole: How did Professor Krassman get shocked into being a frog? The electronic device doesn't even touch his head.
Plot hole: There is a scene setting up the nonsensical resolution of the plot, when the policeman recaps the various baby sightings. First; he already got 'fake' reports he chased, there was a scene about that, let's ignore the fact that certainly he would have gotten more like that and he conveniently for the plot lists just the few relevant ones. Second; the baby was kidnapped at 10 and the baby sighting on the bus happens "in the morning." Then the zoo sighting happens "at 3 o'clock." The construction site closes at 5 o'clock. Even forgetting the superior stamina of the 9 months baby that has been walking a whole day without a break, that's a lot of stretch for the actions as shown in the movie, in particular the time between the bus and the zoo; the bad guys would have been loitering in search of the baby for hours between the bus incident and the moment when he leaves the department store to get to the zoo.
Plot hole: SPOILER ALERT! During the final fight, Joey kills Frank and she reverts back to human form. Abigail tells her she's fine, because Frank was the one who turned her. However, when Frank kills Lambert he does not revert back to human form, even though Lambert was the one who turned him.
Suggested correction: Because it was too late for Frank, who had already turned, Joey hadn't.
If that were the case, then why would Abigail bother explaining to Joey why she reverted back to human form?
Plot hole: In the river scene, Betameche states that his pocket knife doesn't have rope, as it's only available on the smaller model. Yet, around 10 minutes later, Princess Selinia is pulling a retracting rope from the pocket knife, allowing them to abseil down. (00:45:00 - 01:00:00)
Plot hole: It's never really addressed or explained how Shredder survived his death in the previous movie from being crushed in a garbage truck.
Suggested correction: It didn't really need to be addressed, and thus is not a mistake. His hand emerging from the junkyard is enough to show that he survived his apparent demise at the end of the last film.
