I believe it's ok to draw a story out and show the monsters late in the movie. But eventually you should see the monster. Especially since the heroes see the monsters. You would think with all the Alien references that the director would understand that. But perhaps they were trying to be different.Wasn't that the best thing about it? I know far too many movies that go from "awesome" to "pfffttttttt" once the monster/alien is actually shown.
True. Signs was good right up to the last scenes. In fact, Signs has a really good scary moment. When the one character is watching TV in the closet. The TV is showing a recording of kids pointing out the alien. The alien knows they see him through the bushes and just walks out. It's a great scene. So, is the bit in the basement when the lights go out.I totally agree, if it's done right. Alien is an example of it done right. Signs is an example of it done horribly.
