*lol* Just saw this one today too, much to my husband's prodding.
It is good, as far as slasher movies go. You have your romance torn apart by tragic death, lots of blood, crazy rabid zombies that can smell the living blood from miles away, mass chaos, lots of guns... and brains, and a chainsaw. Kind of like 28 days too.
And a sick sense of humor as well. Like... Survivor Island, horror movie style.
