Well, I saw this today. It was very good, and I was brought up on the weekly "Hollywood Musical" on BBC, so came equipped with the musical checklist.
I struggled at first as in my head I wanted to hear (and see) the old timey stuff instead of the contemporary re-imagining that is done in this film. Once I relaxed into it, I loved it and will watch it again. I liked the way the actors' feet were included in dancing shots. I had not imagined either Gosling or Stone as singers or dancers, nor are they perfect, but it hardly matters. The dance with that shot in is lovely.
