I especially loved the role played by Mr Incredible's old car, the 'Incredibile' (like automobile, but incredible..). And of course, after waiting SO long, I loved finally finding out Jack-Jack's powers.
I'd recommend this movie for anyone, but be sure to read the warning at the theater - there are some fight scenes with lots of flashing lights that could trigger photo-sensitive epilepsy. Overall, I'd give this 4.5 out of 5 stars. I really, really liked it and look forward to seeing it again.
