Carriers (2009)

A post-apocalyptic road movie. Its not really a "good" movie per say. The acting isnt very good, the writing isnt very good, the editing isnt very good, there just generally is not a lot of "good" things. But in the end what this is, is a movie about paranoia and as cast reaches its destination, you watch the thin veils of trust fall from them until the last scene. A film that begins with a group in the desert, ends with individuals on a beach.
The premise is that there's a virus that is passed through direct contact with an infected person. Be it a person's blood, skin, or breath, if you touch it you get sick and die. Technically, I think its like a zombie virus, but luckily the movie never really addresses that. If there's one thing I'd be happy to never see again, it's a zombie movie. Anyway, the film begins with a group of four people in an expensive car driving across the country to get to the beach. Why the beach? Because its eden for two of the main characters. The movie is propelled along by these two characters wanting to get to the beach. Wanting to return to paradise. But in there way is Chris Meloni and his infected daughter, a squad of cleansuit survivalists, and the groups own growing distrust of each other.
Thats where the film shines. As people around them get sick and as quarantines get broken, the lines of dialog break down between the characters. Dialog becomes sparse and stilted, tensions and tempers flare, and it gets cool almost in spite of itself.
