Watchmen was mediocre at best. Some phrases and scenes just don't translate well to Snyder's aspiration to stay faithful to the comic. Shallow, out of context lines such as "Whatever happened to the American dream?" (I'm paraphrasing) made me cringe to even think that Snyder had to spell out this conclusion. The whole Vietnam war sequence was garbage! Tropic Thunder did a better job of recreating the look of Vietnam -- and it was a film about a fake film!
The sex was terrible because of its stylization and soundtrack. It was filmed like a bad porno or some 15 year old's fantasy.
The soundtrack seemed like Zack Snyder remarked to himself, "Hey, here are some 60s-80s songs I like, I'm going to make them fit into the film in any way possible."
The acting was terrible, the dialogue was terribly forced, and the only character who I felt for was Crudup's Dr. Manhattan -- a character who is devoid of emotion!
Not to mention Snyder's completely forgetting to mention Ozy Mandias' (sp?)foray into biological engineering that could have been accurately explained in a less than 5 second shot of Rorshach and Night Owl walking through his bestiary instead of just throwing in Mandias' purple hybrid tiger although it didn't develop the plot at all and caused me to question why it was there.
Unlike many of its detractors, I didn't think it was boring and I did go home and flip through the graphic novel. I just thought it was poorly realized and should have waited for a director who had the cojones and talent to make it instead of giving it to a neophyte whose greatest achievement was Dawn of the Dead.
Snyder would have done far better if he would have gone with a grittier, more realistic style that the Dark Knight certainly had. He should have showed us the possibility and horror of this alternate world instead of being incredibly faithful to the comic book and creating a laughable, poor pop-exploitation, shallow, piece of unspectacular special-effects trash film.
And Nixon's nose!? Come ON. They transformed him into a caricature instead of the man who is supposed to be on a five-term streak of striking fear into America's and Superheros' hearts in the film/comic.
However, I did enjoy the ending of Watchmen more as I thought Rorschach's Journal really tied things together and the allusion to renewed world destruction was refreshing.
I really wish I could have liked Watchmen more.
I really wish they would make some Oscar-worthy superhero films.
I may add more later.
Edit:
This guy said it far better than I did.
