I just finished it. I was surprised by how much I enjoyed it.
It starts off slowly but builds into an increasingly better movie as it goes. It's obviously a very female-centric story--not just focused on females but also focused on the sorts of the things that appeal to females--so it may take a degree of patience for a man to sit through, but I found the journey worth it in the end.
On an artistic level, everything about it is top-notch: The performances, the direction, the score, the production design and so on.
I didn't expect much from it--in fact, I even thought I might actively dislike it--but I was pleasantly surprised by how drawn into it I was.
