I thought it was really well plotted, touching on many classic western tropes and character types, as well as some science fiction tradition, but the film managed still to surprise me a couple times: I won't spoil it, but in one memorable scene the movie-world gets a sharp twist to the right that delighted me. Daniel Craig makes a great Clint Eastwood style nameless outlaw and Harrison Ford has finally found his late career groove with this over-powerful rancher character.
I really liked Cowboys and Aliens. Between this and True Grit, the modern Western is alive and doin' jus fine, Ma'am.
