Directed by Zack Snyder. The same guy that brought you "300" which was another Graphic Novel Adaptation.
This compared to how 300 was made, this was a bit different. 300 was short and sweet. While Watchmen was a bit more longer and complexed. Watchmen wasn't all that I was expecting. Yea it was good that they made it into a movie but, it could've been speed up a bit more. There were parts where it did drag for a bit. But when there was action, there was action. It pretty much followed the original story. Some parts were changed. If you read the novel one major change with will be the ending. But I'm not telling you..
They could've at least put some pants on for Dr Manhattan (he is the guy that is all blue). Unwanted nudity
The one performance that I really enjoyed was Jackie Earle Haley as Walter Kovacs / Rorschach. He really brought the character to life.
If you have about 3 hours to spend you should go and check it out. I've seen it twice already. But thats just me. Otherwise read the Graphic Novel.
