That is a hard question for me... since I personally think they botched most of the remakes completely. Quarantine was effective and pretty much a shot for shot English remake, so I can give it props. But overall, American cinema ruins the nuances and tone that European and Asian horror films often present. I think it is like eating Chinese food.... once you've been to China and had the real thing your neighborhood "Golden Wok" or "Dragon Inn" just doesn't taste as good or authentic as the real thing.
I'm a purist I guess. Thumbs down all around for remakes. Even the best remakes ever made don't do for me what the originals did. *shrugs* I guess that makes me an elitist douche bag. Oh well, I know what I like. I like my beer from the tap, my milk from the tit, and my horror from the original director and country of origin.
