Signs was decent...Mel Gibson and Joaquin Phoenix.
Signs wasn’t as bad as the rest. There were a couple of hokey things going on that tried to cash in on the same sort of thing that made The Sixth Sense so amazing, but you could see them coming from a mile away. And good actors can always save a stinker, to some degree. :)
You would think that a species that mastered interstellar travel would figure out how to craft a weapon, or at least a baseball helmet ...
