I disagree. I think the comic was very faithfully adapted, and was basically used as the movie's storyboard. There was really only one change, and that was simply the mechanism used to trick the world that it was under attack and push out Manhatten.
What, by someone "re-imagining" it? When you've already got a great story in the form of a comic or book, the last thing you want it some director deciding he can do it better than the source material. I can't think of when that has ever worked. Heck, Hollywood can't even remake an existing movie and make it better than the original 99 times out of 100.
