I recently finished watching the FORCE FIVE GAIKING tv series (I got it off the net, if you're interested just check ebay or google it, it's out there) and that cartoon is GREAT. Really, it's great. It's kinda cheezy, like Gigantor, but it's totally done straight. Not cheezy for cheeze sake like the old Batman TV series. Cheezy but straight like Inspector Blooper, Dick Strong GIGANTOR straight.
Great story utilizing probaby for the first time a super flying battle fortress (The SPACE DRAGON). Cool story concepts and primo character designs. And I just dig the American dubbing and writing for the dubbed version.
