Most movies getting these threads don't warrant one, but I believe this does. Why?
The Good Dinosaur is looking to be Pixar's lowest grossing movie period. Not only that, but the movie was meant to be a sure fire hit after the massive success of Jurassic Word, a great release date, and following up Inside Out. There was supposed to be a strong Pixarfever after Inside Out, but that didn't show with Dino's opening.
Even with great legs, it likely won't get past Cars 2 in gross.
How did one of Pixar's most expensive movies and probably one of their easier sells come to fail, domestically? The lowest prediction was 215m in the Winter Game, and it will end up falling a good ways short of that. In fact, it'll have a rough time outgrossing (if it even will) smaller studio animated films like Hotel Transylvania 2 and The Peanuts Movie.
What went wrong?
