My absolute biggest thing was the line after the second act break, where

Qwark and Clank both say nobody died in the Novalis destruction.  Don't death star it if you're gonna save everybody.  I don't care that it's a kid-friendly game, it ruins the impact of the event in question.

Other than that most of my issues are minor, but it never feels fully there to me.  The film should help that for most people, though, thankfully.

Oh you're gonna have a LOT of fun in the Hoverboard races!  Until you go for the Trophy, then you might hate yourself.  I beat the required time twice in a row but came in second and it didn't trip.  They lowered the rubber banding in the most recent patch, though, so it shouldn't be as bad now.
