Wow, the comics must be really, really bad. I mean, the movie was entertaining, but the story was a combination of standard clichés and clever twists on standard clichés. The "big twist" was horrible and does not stand up to any kind of scrutiny.
I say this while emphasizing that I still liked the movie, because it was still entertaining and movies to me are about turning your brain off and just enjoying the ride. This kind of movie, anyway. But books, and that includes comic books and graphic novels, are meant to be digested. You take as much or as little time as you want to immerse yourself in them, and in general, the stories they tell have greater depth but also must withstand greater scrutiny.
