Santa brought me Cowboys and Aliens for Christmas. I watched it a few days ago. I was a bit skeptical at first. It seemed like it might be, well, stupid. As it turns out it wasn't a bad movie. The whole concept of cowboys and aliens actually worked pretty good the way it was presented. The special effects were well done.
The weird thing for me was seeing Harrison Ford in a bad guy role. As it turns out he wasn't a bad guy, but it started out that way.
Olivia Wilde is Smoking HOT and having her in the movie made it that much better.
It's worth a watch if you have nothing better to do. I'd give it about 3.5 stars out of 5.
