I love the first one (Eliza Dushku and Emmanuelle Chriqui)
and the second one was awesome too, but my God, part 3 was HORRIBLE. Lousy characters I care nothing about (Am I really supposed to be rooting for prison convicts? I want them to get slaughtered by the backwoods hillbillies!), an ugly forest location (the locations in parts one and two are beautiful by comparison), and cheap CGI gore. Part 4 was a huge improvement over 3, but nowhere near the level of 1 and 2. Bring on part 5.
