I know there are some who find the idea laughable. But I like westerns and sci-fi. I went and watched the movie Sunday with my folks and enjoyed it. I know some will say that for a movie with such a silly concept took itself way too seriously, I found it entertaining. It was rushed in a few places, and there were several plot holes, but I liked it.
It was a good Western, and an interesting sci-fi flick.

I see the potential for some Cowboy and Alien RPGs.
All you need is a Saloon girl, a horse, your ray gun, and a 10-gallon hat. Ye-haw.
