It's by no means a perfect movie. But a lot of worse movies have been commercial -- even cultural -- phenomena. (Yeah, I'm looking at you, Avatar. Hey, just my opinion.)
Scroll down the John Carter Files post for a couple of examples of what I think would have been far superior marketing strategies.
