Solid.
'The Princess and the Frog' makes for a good time. It's nothing incredibly different from the studio's other animated princess films, but still produces what you'd want from a film of this type.
Anika Noni Rose works well in the lead role as Tiana, while it's pleasant to hear John Goodman as Big Daddy; albeit not as a major character. Keith David (Shadow Man) and Oprah Winfrey (Eudora), meanwhile, are welcomed cast members.
The music is rather forgettable, though the (traditional) animation is nice. There's a few moments where it drags its heels slightly, but the pacing is mostly fine. It all comes down to whether you enjoy princess stories, given how predictable and formulaic they are. I'm nonplussed about them, to be honest.
Mid-range Disney, for me.
