My opinion is that Wish’ animation style was a good idea that was poorly executed, that coupled with the poor word of mouth and reviews probably lead to its poor box office performance. There are also some of the general public that has lost interest in Disney, for whatever reason.
The film was not bad, and definitely not one of their worst. It just has really poor pacing problems, and the music is not great. If they wanted it to sound like a Lin Manuel musical, they should’ve hired him. There’s also not really any stakes to the story, it’s hard to keep interest. There are some fun Easter eggs/nods but at the end of the day if they wanted a hit for their 100th they should’ve done a Mickey feature film.
