Cowboys and Aliens

In Jon Favreau's Cowboys and Aliens, all goes wrong in a dusty Wild West town just so that resident humans will set aside their differences (prejudice, extortion, genocide and imperial oppression) and pull together to kick some evil alien butt.
The movie opens when an amnesiac saddle tramp wearing a strange bracelet (Daniel Craig) wanders into the desert town owned by a heartless cattleman (Harrison Ford) and home to a mysterious beauty with a pretty huge secret (Olivia Wilde). The saddle tramp remembers nothing, not even his own name, but is lethal in hand-to-hand combat (think Jason Bourne circa 1868). Soon it's revealed that the weird bracelet is an alien weapon and the only thing that seems to stop these greedy alien gold marauders.
The film is populated with stock characters most of whom have some really important life lesson to learn while riding to the rescue of their kinfolk who were roped like steer and pulled heavenward, presumably to be poked and probed. (Ouch.) Favreau has staged some cool action sequences, including the aforementioned rustling, but Favreau's famous wit is MIA.
