That's the verdict of the Hollywood Reporter, which praises its "engaging" characters and "deep supply of wit".
Screen International lauds the film's "kinetic elan", while Forbes called it "funny, thoughtful and thrilling".
Variety, though, says Brad Bird's film - out in the US on Friday and the UK on 13 July - "is not... the great sequel" his 2004 original deserves.
Picking up where the first film left off, Incredibles 2 sees its cartoon clan of clandestine superheroes fight to have "supers" accepted again by society.
This involves Helen Parr going out to fight crime under her "Elastigirl" alter-ego, while husband Bob - aka "Mr Incredible" - stays home and minds the kids.
That's easier said than done when you have a son who can run really, really fast, a daughter grappling with the problems of being a teenager and a baby only just discovering his own super powers.
Featuring the voices of Holly Hunter, Samuel L Jackson and Brad Bird himself, Incredibles 2 also sees the return of ice-generating do-gooder Frozone and superhero costumier Edna Mode.
The result, says the Washington Post, is an "engrossing and visually stunning adventure" that is "both pop-culture eye candy and a sly critique of it".
Entertainment Weekly is similarly effusive about a sequel it says is both "an eye-popping delight" and "the weirdest Pixar movie ever".
Writing in the Los Angeles Times, reviewer Kenneth Turan says it is "unrealistic" to expect Incredibles 2 to have its predecessor's "genre-busting surprise".
Yet he nonetheless says the film is "as good as it can be" while also taking "advantage of the advances in computer animation since the first film came out."
