I finally saw the new Beauty and the Beast today. I have to say, I really enjoyed it. It walked a very difficult line between remaking the animated version and adding something of its own, and I thought pretty much all of its embellishments worked very well.
There were some good new gags, some nice new lyrics in some of the songs which worked well, and some interesting backstory given to several of the characters that wasn't in the animated version.
The whole production looked great too - like Cinderella (the only other of these live-action remakes that I've seen) the costumes and sets looked brilliant, and there was a nice old-fashioned quality to the big crowd scenes with their hordes of extras.
The Beast looked very good as well - you couldn't tell where the costume and practical effects ended and the cgi began.
The only real weak spot was Watson, who was pretty flat throughout. Everyone else did really well, including Evans, who I wasn't sold on before seeing it.
