.....yeah, I really don't have a collection of westerns. I do like a lot of old ones though (50's - 60s) probably because I'm old myself. I do like some of the more grittier ones from recent years and found some of those from the 80's / 90s don't hold up so well (although perhaps were cool when they came out).
Cowboys and Aliens..... That was one of those I had low expectations of and while it wouldn't win any awards in my book, it is still entertaining. Must be because I like sci-fi as well.
