Non-spoiler summary: Pretty good as an adaptation; it hit most of the book's high points, and I understood the reasons for the things that got left out or changed. How good is it as a movie, standing on its own? I'll have to get back to you on that...

Now the spoiler bits:

- Is it just me, or did anyone else expect Dr. Manhattan to any moment tell someone "I'm sorry, Dave, I can't do that"?

- It took me a moment, as I left the theater, to work out where Laurie got the gun from (since she didn't get it from devastated New York City, as in the book): It's the one she takes off the guard when they're breaking Rorschach out of prison. That still leaves the question: Where the hell was she keeping it?

- One of the things that was thought to make Watchmen the comic unfilmable was the heavy reliance on flashbacks, and that was indeed a problem here -- the movie basically stops midway through to tell Manhattan's and Rorschach's backstories and then resume the main plot. It probably was handled about as well as it could be. Still.

- A lot of "celebrity cameos" (i.e., celebrities of various eras, played by actors). More even that I realized, it turns out after I looked at the credits. One of those TV guys was supposed to be Ted Koppel? The interviewer on the cancer reveal ("Benny Anger" in the book) was supposed to be Dick Cavett? Really?
