I hate to sound rude towards this film, but normally I hate when animated movies only advertise the comic relief and nothing else. Though this trailer was very amusing, hopefully we can get one in the states with more about the plot and other characters.
Gah, I hate that too, but it's a marketing strategy. If the commercial isn't funny, no kids will want to see it, resulting in a huge profit loss. Plus, the target demographic are kids, so they're probably gonna want to please them first and foremost.
