D23 honestly lowered my hopes for The Incredibles 3
I get why they don't want to age up the kids, but oh my gosh, the plot reveal that the kids take center stage and try to prove that they can be heroes again?? They literally did it perfectly in the first movie. So much so that the whole family all very confidently reveal their supersuits at the end of the first movie together. Then suddenly in 2, Helen isn't sure that the kids should be doing superhero work, but they'd already proved themselves on Nomanisan and in the city against the Omnidroid, but in 2 they have to prove they can be heroes and the second movie ends with the family confidently revealing their supersuits together again, just like in 1. And now we're just doing that a third time?
If they'd age the kids even just a bit, could have Violet struggling with the end of high school and starting college and a new life as a semi solo hero, Dash could be going through the start of his freshman year, beginning puberty, tackling his ego and popularity as an athlete but being forced to slow up and hold himself back all the time, and Jack Jack could have something really interesting with the struggle of having to keep his powers a secret at a younger, far less mature and understanding age. How does a toddler deal with superpowers and keeping them hidden from peers? Could've been such an interesting storyline to tackle, but now we have the kids being forced to prove themselves again in a series that begins and ends back to back in each installment. They're literally proving themselves every other week
