Treasure planet was an under-rated film at the time of it's release. The strong mixture of 2D/3D modeling allowed for a phenomenal viewing experience with wonderfully designed worlds, technology design, and in my opinion a great musical score. I think any young kid that hasn't had the perfect upbringing, especially lacking parental figures, can easily relate to the attachment Jimbo makes to a salty ol' pirate that is willing to give him the time of day.
