Everyone has been saying it's good and it is. The superheroes are running around saving the day. Mr Incredible and Elasti-Girl fight over who should haul a thief off to justice and fall in love. Then the city turns against the superheroes: Mr Incredible fails to capture Bomb Voyage because he's dealing with Buddy, his fanatic fan (My name's not Buddy, it's Incredi-Boy!), a suicidal man sues Mr Incredible for foiling his suicide attempt and injuring him in the process, a whole trainful of people sue Mr Incredible for assorted injuries after he manages to stop the train from plunging off the broken track to its death (well - its passengers' deaths). The superheroes are returned to their hidden identities, relocated and told to stay normal. And now the story starts - Mr Incredible (now Bob Parr - of course his name is Bob) is married to Elasti-Girl (henceforth Helen Parr) and they have three kids (Violet, a teenager perpetually hidden behind her hair and who can make herself invisible and project a force field at will; Dash, the primary school kid who can run so fast no-one sees him; Jack Jack, the baby, who appears to be normal), a tiny car and a house in the burbs. Bob works in insurance. He's a hulking man - all that muscle as Mr Incredible has now turned to fat - and cramped into a tiny grey cubicle. There's a great scene when he stands up in a cubicle far too small to swing a cat in and peers out over the cubicle walls and the camera pans back to a sea of cubicle walls. He's unhappy with his job and spends his nights with an old superhero friend, Frozone (Lucius) in his car listening to his police-scanner and doing superhero work on the sly. Helen worries; she wants him to be promoted in his job; she warns her children to be normal because that's what the world wants them to be; she just wants them all to lead a happy normal family life.
There is the wonderful Edna Mode, voiced by the director himself (Brad Bird), the fashion designer who used to design superhero costumes (back in the days when she designed for the gods, not for supermodels, what's so super about these models) and who designs a whole new set of costumes for the Parr family.
The rest is fairly standard. Bob gets a message from a mysterious stranger, Mirage. He is sent on a secret mission to destroy a rogue robot on a deserted island. Mirage works for someone whose office is in the heart of a volcano. Of course the someone turns out to be Buddy, the fan that Mr Incredible spurned back in the real world. Buddy (now Syndrome) has invented all sorts of cool things to make up for his complete lack of superhuman powers. He wants to get back as Mr Incredible. I'm going to stop narrating here because you know the rest and I'm lazy. And it's as heartwarming as cartoons should be, and slyly funny as the better ones are - poking fun at all kinds of stereotypes, from the Italian fashion designer to the disgruntled office-worker to the star-crazed fan to the mad scientist in a volcano to the sulky teenager hiding behind her hair - and sensitive to the normalities (normalcies? that's gotta be wrong) of office life and marriage life and all those other lives that creep up on us. And the baby is really cute, too.
