You know I'm not so concerned with whether or not this movie will be good, but whether or not it should even be made. It's a curious thing with people, they tend to want more of something they like. Whether it be a sequel or a film adaptation, they just can't seem to be satisfied with just one thing.
Watchmen is the first comic book I ever read, with the exception of Maus, but Watchmen was certainly more of a comic book in a traditionally sense. And between these two I learned how powerful a medium it could be.
Because the medium is already visually it would seem to be able to translate perfectly into film, but it really doesn't. Let me plagiarize Alan Moore and say that the essence of the comic book medium is pages and panels. You can move back and forth however you want and their just a certain feeling to it you can't quite get from film.
Personally, I don't have high hopes for this film. I really haven't seen a good comic book movie adaptation, and I'm talking about a good movie, not just a faithful recreation. To me that's an extra area of criticism. It's like when people talk about Attack of the Clones and they say "well you have to admit it had good special effects". That's secondary. First it has to work as a movie. To me neither Sin City or V for Vendetta did that very well. Also V for Vendetta kind of mangled the book, leaving out drugs, a lot of the sexuality, and replaced the message of Moore with the message of the bullshit Wachowski brothers. But I genuinely hope that the movie is a success if only to get people reading the book.
