15 Potentially Awesome Films Undermined By Their Terrible Endings

It seems everyone was on the same page here.

Signs, a thriller about invading aliens who leave strange symbols in Graham's (Mel Gibson) crop field, is an accomplished, visually stunning and dramatically compelling science-fiction work for the most part, but the ending is completely embarrassing on every possible level.

M Night Shyamalan is known for his plot twists and the one he came up with for Signs was, wait for it... the aliens are susceptible to water. As such, these are possibly the stupidest aliens in all of fiction. Why would they go to a planet that's 70% water?!

The survival of Graham and his family is shown to be a divine intervention, which was an interesting idea, but there's one very odd thing about it. Graham had lost his wife some time earlier and one of the last things she said was "Swing away", which Graham retrospectively realises was a hint directed at his brother, Merrill (Joaquin Phoenix), to use his baseball bat on the aliens.

Why wouldn't he have used the bat to fight the aliens anyway? Why did this ridiculously simple and obvious solution require divine intervention (and a tragic bereavement, no less) in order for Merrill to have this idea?

If Signs hadn't had such a bad ending, it would be remembered with more fondness than it currently is.
