Having an animated series is great because it brings kids into the franchise, which means more toys in the stores for collectors, and also you can do lots of wild planets, aliens, and space battles in animation that would be too expensive to do live action.
Plus, I like cartoons.
But if there is a new TAS, I really hope it's old school animation. I don't mean reused scenes and coloring mistakes, but the old fashioned, flat looking, traditional kind. Just because you CAN make a 3D animated show doesn't mean you should. Personally, I think the 3D animation looks weird and unappealing, too heavy somehow. I would LOVE a new TAS with traditional animation.
