What are some really good gory horror movies that are scary and have been out 2000+? like house of wax?

house of wax kinda movies that are really good with celebs in it and is kinda gory and totally thrilling and scary. i really liked H.O.W and everything, but i can't find movies like that that are as suspensful and gory and good. what other are there besides weird ones like hills have eyes and saw?? thanks!!!
