I particularly like the wild west/wasteland feel, but that is not the main reason I like it. The main reason is the morality. The hero chooses to do things the right way rather than easy way, which is something that you just don't see that much anymore. It's admirable.
Trigun is not perfect. While going over the top can be a good thing, Trigun sometimes gets too ridiculous. However, this flaw is not enough to keep me from recommending this anime to anyone.
