Cos Fan Tutti?

The current critique of the movie bemoans a hearing of Cosi Fan Tutti. I rather hear a nice (not virtuoso, but nice) shower Nessun Dorma. Hey, I liked that bit. Sneaking some opera into the film works for me.

Also, however, the film end point seemed a bit obvious and did not include "exploration" of the consequences of the films' finale. Not much character growth or surprise that I can see.
