As I've said, I've watched the visuals for Tangled on different computer screens 'round and about the hat building, and been knocked out. So here's an early squib from somebody who claims to have seen a cut of the feature:
... They maintain the Disney classics (Cinderella, Snow White) look and feel but transition it into the computer generated era. The characters look more like human beings, and less like exaggerated cartoon characters. Rapunzel’s facial expressions are always changing and connected to the actions that she is partaking in. Disney is clearly focused on mirroring Snow White, taking the painting like look, and surrounding it with warm, soothing colors. The watercolor style gives the film a storybook like visual that impresses, but does not dominate the film.
Zachary Levi steals the show as the cocky thief Flynn Rider ...
The consensus of the folks I've talked to is: "They're going for a classically-structured Disney feature with songs, and the songs are pretty good." Everybody is working hard to get the film done under a tight schedule, but they always jam everything through the pipeline in time to hit the deadline. I have faith they will hit the deadline yet again.
Tangled has gone through multiple permutations over its years in development: traditional fairy tale, then comedic spoof (a la Shrek), then back to fairy tale.
I'll be there to see it opening weekend.
