Benedict was right and Bergolio was wrong...

Does He change what He wants from us, though? Or are you still keeping the Sabbath holy from Friday night until Saturday? If you're Catholic, are you following the original laws that don't include any stipulations about Friday's diet, or do you eat fish instead of meat? Should mass be in Latin or not? Is it possible that the change and correction talked of in the movie was as much or more about the Church/humanity as it was God...?

Benedict is right and he should come back as Pope

I don't think either one argued these positions in the movie or otherwise.

They are arguing on what we understand his will is for us.
