I'm seeing a lot of reviews here that totally blast this cartoon. Let me say this, there has NEVER been a disney cartoon sequal that equals out to what the original is. That is Disney's MO (whether or not it's intentional, i don't know). Every single sequal that Disney has ever put out, the artwork completely does not match what the original one was, the actors for the voices, are never the headliners they had in the original, and the sound/songs are never high budget. You have to remember, that when a studio goes to direct to DVD, they will not invest in the high budget that the original had. The quality of these direct to dvd movies, is pretty much roughly just like a TV cartoon.
So, if you expect a blockbuster - don't buy it....but if you know what you're getting into, it's a fun little flick.
