I might actually go watch it. If just for the fact if this movie is successful, it might give the creative development team some sort of "it worked for them!" when a project is flailing.
Also, trailers are usually outsourced and they decide how best to market it sometimes. if they think the demographic is kids, they're going to chop up the movie to fit the concept it's meant for kids regardless of whether it's an accurate reflection of the movie or not....but being said, this movie is totally going to be that PG movie aimed at kids and not older fans. But it should be serviceable if completely formulaic.
