I liked it but ...
I thought it had a lot good going for it. The cinematography, the music / score, dance choreography, pretty much everything that it won Oscars for.
But I also agree that it wasn't good enough to win the Best Picture or Screenplay.
If I were to say it in a single statement, I didn't feel like there was a good middle-glue between the development of the story (the first 2/3s of the film and this much was excellent) and the final outcome.
It wasn't heart wrenching. At most, it was sad that they couldn't make it work, like so many other relationships in real life. I needed this Hollywood tale to be bigger, much bigger than that. I wanted to cry because of the TRAGIC loss of true love. My takeaway should have been "I WOULD NEVER LET THIS HAPPEN!"
Instead I got [spoiler]"Meh, after I went to Paris, I fell in love with someone else and had a child"[/spoiler].
I did like their last glances after his musical piece of "what we could have been", but it wasn't enough.
7/10. Not bad, but I was hoping for an 8.
