Cowboys Vs. Aliens. Holy shit. What the hell is going on? Crappy, crappy movie. I'm not sure why I expected anything different, I'm just surprised at the amazing amount of crap. It has no plot.
Really? I found it decidedly adequate. Had some good parts, even; I liked the preacher dude.
Only part I found actually bad would be the alien chick and the villain motivation. Alien chick was annoying and the bad guys going after gold is silly, since gold can be found a lot easier in places other than earth.
The gold thing is to provide parallels to the Gold Rushes of American expansion. Aliens desire gold, move to a place, mine up the gold while killing natives with superior technology.
I also found it a fun, if somewhat mindless movie. A good popcorn flick.
