I thought the first and second one were decent, the third was a little blah and the fourth just stunk.
I'd take any of the Resident Evil movies over any of the Underworld movies easily though.
That's what it looked like it seemed to be going for, a semi realistic infection movie which seemed pretty cool. I don't think it's just because Starz removes stuff, they do it every so often and it's super lame! Btw, you were supposed to tell me it was terrible so I wouldn't want to go download it now! :
