I loved it, there were things that had to be changed in order to fit into a 3 hour movie but it was done masterfully. I loved the watchman graphic novel and this movie did justice to it, it really did.
I see on the internet people are complaining about certain trivial things, believe me if you are buying into the internet whining, this movie was good and you should see it. Some might be scared to see it, assuming it will be a travesty such as many adaptations, but It wasnt. People who say it was are just completely out of touch and unrealistic.
Some stuff was lost (SPOILERS):
-Most notably, the ending. The Giant squid that was supposed to trick everybody into thinking aliens attacked is replaced by something that I believe is more sensible and actually improves the Watchmen story, but most importantly It was more suited for the big screen adaptation. This was NOT a negative perversion of the original, it accomplished the same things and didnt harm the material at all I swear to god. Anybody who says otherwise is being far too picky and unrealistic.
- Captain Metropolis isnt included in the 1970s attempt to form a league of masked heroes in which Dr. Manhattan meets Silk SpectreII for the first time. Instead his character is never shown outside of 1940s flashbacks and his role in that meeting is absorbed by Adrian Veidt which didnt fit I felt as well as the overly optomistic Captain Metroplis, but it was done in such a way that the change can be excused.
-The incredible focus on unimportant characters such as the psychiatrist, newspaper vendor, etc have been completely removed and they no longer have prolonged scenes and character development in which they are the focus. Thank god for that, that would require an extra hour at least of scenes that wouldnt really work for a movie, people would criticize the watchmen as too long and too boring if these werent flattened out.
Im amazed, I really am, that this movie was able to do such a good job transferring such an amazing story to the big screen. In my opinion if Alan Moore never watches this movie and acknowledge that it wasnt bad, Ill be pissed off. If I was Alan Moore I would be so freaking ecstatic that such a faithful adaptation was made of such a difficult to portray graphic novel.'
If you havent seen the movie, GO WATCH IT BEFORE IT LEAVES THEATERS. Honestly.
