Cowboy Bebop is what kicked it off for me. Outlaw Star was a lot of fun, but coulda used more cowboy style shit on the soundtrack. Watching Space Dandy now and while it's not quite a space western, it's pretty fun to me.
Anything else I should check out?
votoms is basically every 80s action movie wrapped into one show and it rules. the first arc is about killing cops in a cyberpunk megacity and surviving fight clubs and shit
