JudasIscariot: Signs wasn't too bad really. They didn't go overboard with the usual aliens-invade-so-now-we-have-to-show-off-their-ships mode. And this was before Mel Gibson started going batshit insane.
Surely you mean that it was when he could still hide how batshit insane he is?
Also, Signs had a poor twist, much as I appreciate M.Night's work, it irritated me the second watch through.
Although his last film was pure comedy. Oh wait, it was supposed to be serious... so serious that the actors forgot to act. Although it does have a cameo by none other than Brian O'Halloran, which I spotted despite only seeing the side of his head! (I guess I've seen Clerks etc. too much...)
