High Plains Invaders

It's "War of the Worlds" set in the Old West. Just as a legendary train robber is about to be hanged in a small Western town, a bunch of mechanical creatures invade the town and kill everyone in their path. A mother ship also begins to hover overhead. The outlaw and several others desperately battle the space invaders, but they quickly get picked off one by one. By the time the dust has settled ... well, you can guess the outcome. A Canadian job, this has some interesting characters but very poor CGI for the invaders. And the action sequences are clumsily staged. You never believe for a moment that humans and monsters are battling one another. A little more production money and attention to script details would have helped. As it is, we were just relieved when it was over.
