The Adventures of the Galaxy Rangers was not the best cartoon ever produced, but it was better than a lot of better known, toy based cartoons produced in the mid to late 1980s. Aimed at the teen/pre-teen market rather than little kids, and without a huge merchandising campaign to back it up, the Galaxy Rangers has become a short lived, little known piece of trivia from the 1980s.
Overall, the show was well animated, on par with some of the products from Japan that were being introduced around the same time, and offered decent, if not deep, story lines. Odd things about the series include the whole "wild west in the final frontier" aspect and the fact that some of the character designs borrowed a little too much from popular western movies.
With its odd premise and limited distribution, my local station showed it at 5:30 AM, this show was never destined to become a well remembered hit. It was, however, better than its review score on this website would indicate and I give it a solid 8.
