The ending (spoiler)

I saw this film recently and I have to say, the ending feels very ambiguous. Belle isn't all that thrilled with the Beast in his human form, and when he holds her in the end, she has a look of uncertainty on her face. After all the fairy tale elements and lovely chemistry, the happy ending is tentative, at best. This isn't a criticism, per se, but it just struck me as a little odd. What do you all think?
