Haven't seen it. It got panned pretty thorougtly by critics and it bombed at the box office, which doesn't inspire a lot of confidence.
I'm moredately interested in Westerns myself, but I wasn't impressed by some of the trailer which show exploding trains hurtling through the air and stuff. I don't really think modern action movie sensibilities quite match the genre. I've also got mixed feelings about Depp playing Tonto. I mean on one hand he's a good actor, but seriously Hollywood, a white guy playing an Indian in 2013?
