From the title alone, we can assume it's going to be two guys with guns versus the world. Action, action, action! For best results, go in expecting an action flick and you should be content. Normally, I'd be more than happy to come up with a witty title-based remark that leaves you hanging, but with a title like 2 Guns, the best I can come up with is something like like "is it shooting blanks, or is fully loaded for an assault on your favorites list." Sorry.
