It's awful to even think about..
This is easily one of the worst movies I've ever seen.. and I've seen a LOT of horror movies. I can even forgive the fairly poor film quality because I'm used to it, but there are SO many problems..
1. The Blood is very, very fake.. it looks like ink even close up
2. (minor spoiler) What kind of craptacular concept is vampire blood makes you a zombie?
3. Most of the zombies were very, very corny. The make-up was actually pretty decent, but I swear they were the worst actors ever.. and that's saying something for being a zombie.
4. (minor spoiler) *picks up cell phone* "hello! I'm trapped in the closet.. with nothing but my cell phone! I need you to call the police!"
5. (minor spoiler) The car scene was awful.. I might just be picky, but the car was already slowing down when she "slammed" on the breaks.. and even then you could tell the car was practically stopped alread and he rolled casually down the hood!
6. (major spoiler) When he was pinned to the tree.. it went from the middle of the night.. to the fastest sunrise ever, to broad daylight in around 7 seconds..
The movie was far from entertaining.. and I'd only recommend it to someone who I really didn't like.
