Meh, I've got it and I just think it's O.K.
Most comic adaptations of movies aren't anything special, just a printed version of what you see on the screen. Except, perhaps, for the fact that occasionally you'll see one that has a couple moments that aren't in the finished movie, usually because the folks working on the comic have a draft of the script that isn't getting quite as revised as it does on the set. In this case, there's the extended stuff on the farm that was cut from the finished film. I'm still trying to track down the 'prequel' books DC released for the movie explaining what went on with Ma and Lex and whatall prior to the start of the film - I'll probably have to wait for the TPB.
But as I said, it's pretty cut-and-dried, like all film adaptations you see published nowadays. I wish somebody would print a kick@$$ film adaptation again like Marvel's STAR WARS.
