Crazy, I really must be a Pixie Duster™.
Wish was by far my favorite animated movie since Princess and the Frog. And if that wasn't shocking enough, my biggest issue with it seems to be the one thing other people liked: Chris Pine. The writing for Magnifico is all over the place, and what he "sings" about in his song has very little reflection on his actions shown in the movie. You can tell that there were several rewrites of this story, and I think Magnifico's entire character shows it most obviously. Also, if they wanted to return to traditional villain songs, they should have cast someone who could actually sing it. It was way too speak-sing for me.
Outside of that? I think the movie was really strong. My only other critique is that we could have used a 'Welcome to Rosas (Reprise)' establishing the new kingdom a bit better. I'm seeing it for the third time tonight with a different group of friends, and I'm actively looking forward to it.
If you're on the fence on this one, I'd recommend seeing it for yourself and forming your own opinion.
