The short is pretty good, interesting character designs that makes it feel unique and the story is one of the strongest compared to recent Pixar shorts.
I'm a bit weird with Incredibles. With the first one I loved the mundane 'family' moments but the action bits I just found myself admiring the animation and sort of zoning out of the 'plot'. There never seems to be any real sense of danger. I think Incredibles 2 felt the same way where the best parts really just involve the dad and kids interacting with each other. The Mum character has an elevated role in the sequel which is a shame as she's not that entertaining.
I just love the animation though, Brad Bird seems so incredibly good at adding those 'extra' little details that are often missing from other similar films.
It's really just more of the same and for many people that will indeed be incredible.
