Maybe it hinted at the quality of the dialogue, but none of the trailers gave a hint of the character development, or the complexity of the plot. It gave no indication of the real themes behind the movie.
A trailer for Watchmen can have tons of really cool sounding dialogue, but until people see the story play out they'll have no idea what this really is. You can show Rorschach say cool-sounding lines, but you cant convey why he says them, and who he is, in a 2 minute trailer.
And honestly, i'm kind of glad. I want the general public to be tricked into seeing this movie. I want to be in a crowded theater, and overhear people whisper as they slowly realize just what kind of movie this is. I imagine that'll happen at some point near the second chapter, when they really meet The Comedian. And maybe I'm naive, and I just like Watchmen too much, but I really think that if most people give it a chance, they'll love Watchmen. I think if the movie can pull people into the theaters, they'll come out loving it, despite it not being what they expected going into it. Of course, maybe i'm giving American audiences too much credit.
And once again, i'm still confused as to what you dont like about the trailer's look. What scenes specifically bother you, keeping in mind that slo-motion is used only twice. What about it's aesthetic feels wrong to you? How should a Watchmen movie look?
