Alright well not even Pixar can win them all. Their teaser for CARS was a misfire for me, but I did end up loving the movie.
In contrast... here's a teaser for Princess and the Frog that at least showed Tiana, but failed to spark interest with Ray the Firefly. People didn't love that character until AFTER they saw the movie.
Here's an odd one for Tangled. Just hints but not even a title.
The Tangled teaser everyone remembered they hated but couldn't place why (because it was too Dreamworks most said). But again... it focuses on our main characters.
Wreck-it Ralph on the other hand relies entirely on scenes found in the film.
That brings us back to Frozen. A teaser that teases a movie that doesn't exist. Kids will be enchanted by the snowman and reindeer but that's not the movie they're gonna get is it?
As said before, it would be the better decision for Disney to sell the movie honestly rather than give us a jokey ad that doesn't even show us the main characters or even the real tone of it. This is supposed to be a movie based on a story by Hans Christian Andersen?
