Watched this the other night in the movie room, and really enjoyed it. It's deliberately highbrow, with Russell Crowe and Kevin Costner lending gravitas to the role of Cal-El's fathers. And grungy - it reminds you more than a little of the Batman reboot by Chritopher Nolan. Oh wait - he's an executive producer - that's why.
Halfway through I realized I was taking this movie seriously, and not treating it as a comic book movie. I am looking forward to the next installment, when we don't have to wade through the origin story.
