Hills Have Eyes had a whole lotta new scenes, including the kick ass village scene as a good example, plus the acting was very believable, the Hill people were intimidating and the film just felt so much more atmospheric and better than the original
Hills Have Eyes is the best remake period in my opinion
Dawn of the Dead was nothing like the original either
I'll gvie you the NOTLD though, it was alot the same, but still a fantastic film
Never rated The Thing myself, but that's just my opinion
