I'd say so. Its a great anime. Did not do too well in Japan due to it being too western or something along those lines. Its fairly upbeat and a decent combo of humor and action. If you like a main character with a questionable past, wild west setting, and other characters having little quirks here and there for fighting, you should watch it. I heard the manga was good as well.
