I agree with Laz,

Any more details from the graphicnovel and Watchmen would have been complicated for nothing and too long.  We were 7 people together to see it and only two came out with reservations, the rest liked it a lot.  I was warned before getting to go that the ending was messed up, but in the end I think it made perfect sense to do it this way, it was more ellegant than the graphic novel.

I enjoyed this movie and would see it again, will def purchase the DVD.
