This is one of the more underrated Japanese movie franchises. Both the anime and the live-action movies got a lot more visual style and fun than most would give them credit for.
I rented this on DVD a while ago just to see if it was still as good as I remembered, and yeah, it sure was. I love all the weird vehicle and weapon/gizmo designs, and extra super bonus points for the Toshiro Mifune-inspired bounty hunter who popped up every few episodes. Too bad the show didn't have a longer run.
