Though film fans often seem confused about exactly what constitutes a legitimate movie plot hole, a genuine leap in internal logic can sink a movie faster than just about anything else.
These plot holes, on the other hand, weren't quite as immediately obvious, even if they were impossible to "un-think" once you realised them, and may irreversibly alter your perception of each film.
Some of these holes sustain because they don't interfere with the bigger picture, whereas others are so egregiously bad or weird that they now become a distraction every time the movie even hints at them.
From a certain famed fantasy author seemingly breaking her own rules to basic physics gone wrong and protagonists impossibly surviving for a happy ending, here are 10 giant plot holes you didn't notice in 2016's biggest movies...
10. Why Is Newt Allowed A Wand? - Fantastic Beasts & Where To Find Them
Early on in the movie, the audience learns that Newt Scamander (Eddie Redmayne) was expelled from Hogwarts for endangering human life with a beast, yet he's still allowed to keep his wand and perform magic throughout the film.
Fans began to question this almost immediately, considering that Hagrid (Robbie Coltrane) was expelled from Hogwarts as a youngster and had his wand snapped in two for his apparent transgressions, so why didn't Newt get the same treatment?
J.K. Rowling was bothered enough by this that she responded to a fan on Twitter, claiming, "All will become clear. Trust me", but to be honest, this just sounds like an after-the-fact save, that an explanation will be added into a script for a future movie.
Until we get a satisfactory explanation, this remains a plot hole.
