Forgive me if this is long, but I have a few things that I would change if I were the producer:
- Name the other pups (for starters . . . . or at least make them recognizable with collars or something like that)
- Not as much magic and more adventure (mainly that whole "becoming one with the tree" thing . . . *shudder* Oy, that was too much. It's a journey, so give us more action and adventure! The story made it seem like a kiddie ride instead of a roller coaster.)
- X out the singing dogs (Muru's song can stay, because mice are awesome! The background song (like "Taking You Home") was fine as well, but no singing dogs/wolves. And if I hear Balto singing in the next Balto movie . . . . or if someone makes "Balto: The Musical" . . . . . . *stab*)
- More focus on Balto please! (Yeah, it's Aleu's journey and all, so what about Balto's journey, ne? What's going through his head when he starts looking for his headstrong runaway daughter? How does he feel about returning to the "wolf" part of him? and so on . . . .)
- X out the unnecessary characters (the yipping scottie, the wolf trio, Muk and Luk . . . need I say more?)
- Add Balto's return home (what really happened? Jenna/Boris/Muk and Luk's reaction to the news? etc.)
- . . . um more explanation about Aniu (Was Aniu really the WW from the original movie? Why is she so close to Nava? (really, I'm curious about that one!) and so on . . .)
Um . . . I think that's it for now!

May add more later!
