Signs is a scary little movie. It has some plot holes to be sure but it holds up as a horror/sci-fi Hitchcockian thriller. Ignore the jerk director and enjoy it for what it is.
Warning: At 37:54 Eric tries to drop some knowledge about the movie. After hearing this, Brother J decides that the dropped knowledge doesn’t help the plot holes and actually hurts the watching experience. So there’s that.
You’ll also hear the sounds of hell and the sounds of dying cosmonauts (all tricks, no one was harmed in the making of these recordings – as far as we know) Housekeeping starts at 1:01:45, you’ll hear some train stories.
