The thing you need to know about "Signs" is that this is probably the first alien invasion movie in a long time that isn't any fun at all. Also, you need to watch it twice.
See, the first time you watch it, you end up disappointed. It takes a good ninety minutes or so to get scary. And it's a more sublime kind of scary than the "Anything can happen, oh, %&$@!" kind of scary you might be expecting.
So watch it again, later on, now that you understand the tone of the movie. See, it's less "Oh, no, the aliens are coming!!!" than "Independence Day" as a clumsy (but effective) 9/11 allegory.
