I'm a huge western fan, especially those made in the past 25 years or so. I say that, since I think old westerns are so completely fake (sets, actors, clothes, etc.).
This, however, is probably one of the worst modern westerns I've seen. I actually shut it off a few times out of sheer boredom, but finally finished it. Chris Pratt is a great actor, but seeing him in his fake clown beard (the poor boy obviously can't grow facial hair) was terrible. The acting was so-so and the made up story line with this boy and girl was just stupid.
Also, New Mexico didn't become a state until 1912 (same as the state I live in, Arizona). So why did they keep saying the state of New Mexico and getting "out of this state". Little things like that are just lazy. But I guess if you're going to make a cartoon western, you can say whatever dumb thing you want!
