I expected that from the pre-release crowd, but never read up anything on this movie until its release. Post-release people are still saying it's bad, but I think that's where they're showing how biased they really are.
I guess you're right in that the vocal majority does not represent the overall majority opinion. To receive a 6.5 on IMDb is nothing to wince at for a remake, especially since I didn't find it particularly enjoyable the whole way through, though I thought the production itself was pretty well done (with the hiccup of how they went about one part I mentioned earlier).
