After watching all of the current season 3 episodes I can say that the reason I don't like Leo's new voice is because it doesn't sound like a teenager anymore. It is really jarring when you have all four turtles talking and then Leo's voice comes in at the end and its so deep compared to the other three. It's even deeper than Raph's voice!

Also, Seth Green is one of those people who have done so much comedy that no matter how hard they try they can't sound serious.
