Watchmen: The Ultimate Cut
An intelligent, complex, bold and layered plot, coupled with visually striking imagery turned Watchmen into a rather impressive effort, despite its flaws.
While The Ultimate Cut of the film is the best version, and fixes a lot of Snyder's errors, Watchmen stands out as not only a great comic book movie, but one that changed the game, because it went far beyond our expectations for what the genre could give us.
Up to that point, and perhaps this statement still holds true, there had never been another comic book movie quite like Watchmen. It was a comic book movie strictly for adults only, and one that was packed so full of substance that subsequent viewings were absolutely necessary to digest everything.
