From the paper:

The French have a word to describe "Ratatouille," the tale of a provincial rat named Remy who becomes a great Parisian chef. The word is "génial." Not genial as in cheerful, although Pixar's latest animated feature is certainly that, but génial with an accent, as in brilliant or inspired.

Don't we have a word to do this job?

Brilliant, inspired. Here.

The film is about French anthropomorphic rats. Maybe génial is the mot juste.
