I enjoyed every minute. The movie is based on a comic book and lists seven additional writers; I imagine these guys made up lists of their favorite western and SF clichés and then played them absolutely straight...and made them work! One quickie example. There's one man who doesn't know how to shoot a gun but is trying to learn. So we get two brief scenes showing him shooting at bottles on a log and missing every time. Now, everyone who's ever seen a movie knows that's a set-up. At some crucial moment, he's going to fire the perfect shot that will make a big difference in whatever's happening at the time. We not only know it's coming, we want it to come. And when it does -- oh, how satisfying! It's an Ah, yes! moment. The movie is filled with just such moments.

No more just now; I don't want to give anything else away.
