Movies That Would Be Way Shorter If Characters Were Reasonable

We get it, most movies need a central conceit in order to make the plot actually work. No one is saying that every movie should end in five minutes with a phone call or the decision to "not stay at the creepy mansion." What gets frustrating is having to watch a bunch of movies that only work because the characters involved are unbelievably dumb. It's kind of like these unrealistic movie details that will never stop being annoying.
