This is not a flattering movie trailer.
The thing is, Frozen was done by the same people who did Tangled, and those people presumably did this trailer:
…which is also not flattering, not to mention completely obscuring the fact that Tangled was a great movie. Particularly the bits with Maximus. You know, the horse? The insanely awesome horse that got maybe three seconds of time in that trailer?
So it might not suck.
