Fortunately the question wasn't which remakes/reboots is better than the originals, because I don't think I've seen any that is (but the way my mind works right now I wouldn't trust it, so...)
The Dawn of the Dead remake was a GREAT movie; funny, splatty, shocking! And it was a perfect remake in that it took many of the important parts of the original and transferred them to a current environment with updated effects.
When we watched it, the guy next to me couldn't have watched many zombie movies (or scary movies, for that matter)! He screamed like a little girl 3 times within the first 15 minutes, scaring me more than what was on the projection screen each time...
