Cannot say how truly dead it is, but judging on how I have yet to see any sane adult say almost anything good about Wish, I assume it’s nearly on deaths doorstep already. With all other 3D animated Rickey Rats original and not subsidiary company films you had adults that liked them but I have yet to find a single adult with no mental defects that likes/liked Wish.
If Wish is setting the standard for their 3D films, you can beat it’s on death’s door, if not far from it.
