Evil Dead (2013)

I'm not sure when hacking off infected body parts yet surviving to fight evil became a horror film staple but Evil Dead hacks and survives in droves. It adds even more unbelievability to this remake of 1981's The Evil Dead while the new back story adds nothing (unlike the remake of The Hills Have Eyes). There are plenty of homages to the original (from the cellar to the tree to the chainsaw) so watch the original instead for frights and laughs - two things it has in droves.
