Saw this yesterday and I loved it. I am a huge animated purist but this was really well done. I always wanted a longer "falling in love" story in the original and they really did that very well here (library scene was my favorite, like many others here). Plus, I really liked Dan Stevens as the Beast. With every word he said it was so easy to see the petulant, spoiled prince underneath and sometimes in the original, you really didn't see that. You only see a big scary screaming monster or a cuddly teddy bear.
I liked Emma as Belle even though her voice was obviously auto-tuned rather heavily. I loved how she really looked like she was falling in love with the Beast especially during the ballroom scene. The way she looks at him...it was really well done.
It's a bizarre conundrum for me. As much as I don't think it's necessary to do remakes of the animated classics, I'm enjoying them immensely. If Disney is going to continue doing such a thoughtful job in their remakes, then bring on Lion King.
