The other thing that bothered me about the climax of Signs is the fact that this creature that's fast enough to scale buildings in a blink of an eye and strong enough to effortlessly hoist a child in one outstretched hand can so easily have the shit beat out of it by a regular-ass dude with a baseball bat taking a swing at it every 15 seconds while it just stands there taking it. Even before it got any water on it it was having its ass handed to it. It wasn't even a fight.
I still think the early moment of the scene when you first see the creature reflected off the tv is really cool though, to me that's where the movie peaked.
