WATER-PHOBIC ALIENS
Signs (2002)
Things were nice and creepy in M. Night Shyamalan's crop-circle frightfest, until the big-twist maestro served up his lamest surprise to date: aliens that looked like they stepped out of an Ed Wood movie. And what's more, their big Achilles heel was...water. Good ol' H2O. Now, do you think a civilization smart enough to perfect interstellar travel might've done a quick scan of the planet they were planning on invading? Then they'd have discovered it was covered with the very stuff that can kill them. The director's precipitous fall from box-office grace can be traced directly back to here.
