The difference is, much like Zack Snyder's version of Dawn of the Dead there are similarities, but a whole different situation. I'm going to keep an open mind about this until I see it. However, almost anything with the "3-D" logo attached to the title is almost never a good sign. Snyder proved you could break out of canon with a title and make a damn good Horror flick. We'll just see what Haig and company can do with their take on the old chestnut.
