I mean, there are some good laughs in the trailer, are they stupid laughs, yeah, but most laughs are stupid. But let us not forget that Dreamworks Animation, the studio, making this film brought us "Shrek" and "Kung Fu Panda," two awesome animated features.
People who whine about 3D glasses need to relax. Millions of people wear glasses every day, and get along with life just fine. So what is the problem with wearing coold "Back to the Future part 2" shades for 2 hours so you can marvel at the silver screen.
Could it suck? Yeah it could, but if this film get's one good review, I'll be there opening day.
