Let's face it, this is a fairy tale and if you don't like such things then you won't like this movie, but, on the other hand if you do love a good classic bedtime story where a young girl is cursed, her family is looking for the perfect prince that will save her, love is, as usual, playing games, disguised in a charming man that is not a prince, while the prince is really a pig and the pig-girl is just lovely (even with the nose she looks lovely, she is not disgusting in any part of the movie), and the curse is in fact nothing more than our fear of not being accepted for our physical characteristics.
So, it is quite a simple story, yes, but nowadays, when 15-years old girls are asking their moms for nose jobs, I think it is not so bad to have a movie about loving oneself and accepting that pig-girl or not, you don't need anyone else but yourself to be happy.
