Perhaps I'm a bit too much of a fanboy... but I wasn't impressed
I am excited to see the directors cut, and Tales of the Black Frieghter and Under the Hood, and I'm sure I'll see it in theaters at least one more time however I have issues with the film.
Five Reasons - and I'll try to keep spoilers to a minimum
1: Pacing - Cramming all of Watchmen story into a 3 hour movie is no easy task. The overall plot points and most of the character development was there, but the movie was really choppy... I would have liked some smoother transitions, and better cinematography.
2: Soundtrack - Someone should be shot for the blantently noticable soundtrack. I felt at several points in the movie the soundtrack took away from the action/story
3: Matthew Goode - Take an acting lesson... it'll help
4: Ommisions of small little bits in scences they otherwise did verbatum - For Example - The ommission of the Comedian's Best line ever - "See you in the funny pages"
5: Lack of Squid - The squid ending makes more sense, nuff said.
