In some ways, I think this actually looks better than the original.
Don't get me wrong, I love the classic version and wouldn't change anything in it for a million pairs of rose colored classes, but I have to admit that there were a few things about it that were a little flimsy. Lion-o aging from child to adult in sleep stasis, changing/forgotten powers, a planet being destroyed and reforming exactly the way it originally was, characters breathing in outer space... The list goes on and on. Even the voice acting (which was great) suffered from having about six voice actors doing voices for thirty characters.
This looks like there's actually been some decent world/continuity building put into it, it has good character design, it's better animation than a lot of the mass produced crap I see these days, and sounds like good voice acting. If the trailer is to be believed, it looks like there are pretty high production values. Count me in.
I do wonder where Snarf is, though. And Cheetara's boobs are too big.
