Good lord this movie bugged the crap out of me. The animation is a mixture of fairly good to one of those awful animations three year olds watch. They throw in some very obvious adult humor at times and reference movies that feel so forced and completely out of place. Ex: There are skeletons of Jack and Rose from Titanic in one scene and they mention Godzilla and Mothra in another. They were trying to be funny I guess, but it was just so groanworthy! Also why would a character say "I hate to see you leave, but I love to watch you walk away"? YOU ARE IN THE OCEAN SAY SWIM AWAY!!! Moronic! There is no way I can believe even in a cartoon that a train would be able to work underwater with rust. I can't suspend my disbelief for stuff like that. Also there are a few musical numbers for who knows what reason! They just throw them in there and it's not even a freaking musical. The voice acting doesn't mesh well, but some are typically great in other things. Even though there were a few brief moments I liked it ultimately pissed me off! Anyways don't torture yourself with this one!
