The animated show is such a materpiece, but it's still a kids show. There was potential to flesh out some of the more adult themes (war, romance) the show touches on in a way a kids show couldn't. But other than that, they should have stuck very, very close to the original show.
Well, maybe I wasn't "highly excited", I was pretty sure they would screw it up.
But what I couldn't have expected was just how badly they would screw it up. It took less then 5 minutes of watching to realise that the show will be bad (as they open with a prime example of "tell, don't show") and it really just went downhill from there. I think I dropped it on episode 4 and it took a lot of forcing myself to even get that far.
