This is not to say that the sequel is as good as the original. At many points the film feels like it's trying too hard. The action scenes are so fast that I felt a little numbed by them. And the plot seemed recycled from other superhero films, including the original: what is the place for superheroes in our world?
The film picks up right from the end of the last one. Superheroes are illegal, and when Mr. Incredible (Craig T. Nelson) and Elastigirl (Holly Hunter) attempt to stop a bank robbery, they are admonished for wreaking destruction, and told the money is insured. Their funding is cut, and they are living in a motel. They seem resigned to getting regular jobs until a billionaire who loves superheroes wants to get the law changed. He needs just one hero to prove his point--Elastigirl.
So the film bifurcates. Elastigirl has adventures involving stopping a runaway train, saving an ambassador from a helicopter attack, and unmasking the Screenslaver, a villain who hypnotizes his victims through a screen. Elastigirl thinks it's been too easy, and savvy viewers will agree and have this figured out beforehand.
The other half of the film is the family's domestic life. Mr. Incredible has been reduced to taking care of the kids, and he discovers that the baby, Jack-Jack, has superpowers. Many superpowers. He can shoot lasers out of his eyes, erupt into flames, travel through different dimensions, and multiply into several Jack-Jacks. Much of this is shown off in an amusing fight with a raccoon.
The baby stuff is very funny, and I enjoyed hearing the little kids giggle at it around me. The action scenes, as I said, seemed old hat, though the animation is breathtaking. A whole new bunch of superheroes are introduced--my favorite is Reflux, who has such severe heartburn that he can vomit lava.
If there is an Incredibles 3, I hope they veer off in a different direction where the debate about the legality of superheroes is resolved.
One more thing: I haven't heard too much about this, but Elastigirl, in her costumes, has the kind of body that women have spent decades complaining about. She has a figure more ridiculous than Barbie, with possibly 44-18-44 measurements. The New Yorker's Anthony Lane did write about dads possibly feeling a little awkward getting turned on at a kid's animated movie. Of course, she is elastic, so maybe that's just the dimensions she wants to be.
