The real test of a movie is how well it performs in the first and second weeks after launch. Word of mouth and all that. Some films like How To Train Your Dragon can recover from a weak opening and show extraordinary strength down the road, but that doesn't happen very often.
The Tomatometer rates Angry Birds at a Rotten 43%. Zootopia, Fresh, at 98%, The Jungle Book, Fresh, at 95% ---- and. if you have taken your kids out to see Zooptopia and The Jungle Book, there isn't much of anything else out there for them right now.
Disney doesn't need Angry Birds.
Not when it is adding originals like Zootopia, Frozen, and Wreak-It Ralph to its animated cannon and vivid live-action remakes of films like Cinderella and The Jungle Book. Not after it after added Pixar, The Marvel Cinematic Universe, Star Wars and Indiana Jones to its roster.
