Didn't think my first comment on a porn site would be complaining about Incredibles 2, but I completely agree with everything you're saying. Used to rewatch the first one with my dad, we both saw the 2nd together and could _feel_ the disappointment radiating from each other. I just kept asking myself ”why does this exist” and never felt like I got a satisfactory answer.
The saving graces are that it looked good, and that it seems to have inspired a ton of great fanart, yours especially.
