Here's what I don't get. If they were going to go with actors that didn't look like the characters why not just use the original voice actors? They'd at least act and sound exactly the same. Though I do like Noah Ringer for Aaang, and that particular character needs to know how to fight. And Dante Basco (Zuko) is a bit too old...though he does look young for 34.
