I've just seen it after along and tedious ordeal at the cinema involving power failures, long lines, and a midnight show.
I was very excited to watch it but also very skeptical from what I've seen in trailers and the changed endings and general foreshadowing over the internet. In the end, I'm very pleased.
Considering that Hollywood is responsible for this, Watchmen manages to avoid many cliches. The final product was very loyal and true to its sources.
The opening scene was magnificent. The exposition scenes were well made.
The mostly anonymous cast did mostly great job, they looked the part, they played the part.
I was slightly annoyed by some of the action scenes and while I loved the soundtrack, some songs felt out of place (though that didn't stop me from singing along!).
The new ending held most of my fears, but I think they pulled it off well.
All in all, it was a different experience from the comics, darker, rooted in our times, still loyal to the spirit.
I wish the other Moore comics had received similar treatment.
