From the story presented in the trailer thus far, it likes more or less like a reverse of the first movie.
Helen Parr wanted to stay home and be a normal person raising the family, Bob Parr still longs for the glory days and does Superhero stuff.
Now its Helen that's playing Superhero while Bob is raising the family.
If this was shown to me around 10 years ago, I would have lost my shit, now.....I am not feeling it, mabye on DVD, but I am not that hyped for the movie. I guess its too little, too late. They should have done this earlier instead of CARS sequels.
