I love The Incredibles. It is the best version of the Fantastic Four that has ever been on the screen. The key to doing a good Fantastic Four story is that beneath all of the epic superhero antics it is, at heart, a family story.
This new trailer looks very interesting. I like the Mr. Mom-like elements, where Mr. Incredible has to become the stay at home dad. Something tells me that a lot of parents will have the same feeling that Mr. Incredible has regarding "new math."
The animation looks great and so far I don't see anything that is a red flag. I am cautiously optimistic.
