Dead Within

First, this is not a zombie movie, even though it really is.

What I mean by that is that there are zombie-type creatures in this movie, but the movie is really the characters and the paranoia they experience as they are trapped in a house after an apocalyptic event.  It's basically a one-set movie with the majority of the time being spent with two characters.  The movie starts out with four characters and a baby, but then flashes forward and backward in time telling the story of what happened to the other people.

The acting and filmmaking are good, but if you're looking for a zombie movie, this film may not work for you.  It didn't entirely work for me.  It requires a lot of patience and might have been better being a short film.
