I think the reason why Watchmen was considered un-filmable in the form the comic was is very evident in this movie. The Rorschach psychiatric sequences, the history of the characters ect needed fleshing out and in film time that's impossible unless you do a trilogy, or at least a part 1 and 2. and with the story telling technique of filling in the blanks that Moore used I don't believe people would have hung around for a sequel. thats why i think i would have liked to have seen more interpretation that verbatim.
As others have noted, the best way to adapt the source material was a mini-series.
In a perfect world, WB would have told Snyder in effect "let's do an HBO-style version of 'Heroes' or 'Lost' with this."
Still, minor quibbles aside, it was an enjoyable film and probably as good a movie adaptation as we were going to get.
And, in fact, if some of the rumors are true, once Snyder adds in the extras for DVD it might be practically a mini-series.
