Okay I've finally had the chance to watch it, I agree with most of hengcs comments but I don't see how anyone could regard it as pornographic, sure there are the scenes which obviously represent making a porn film but I've seen more explicit nudity in some pop promos.
Come to think of it, a few people are bound to think it's sick and pornographic without even seeing it!
The musical numbers, great idea like a cross between a Bollywood film and some Thai films. Strange film in some ways, very sad yet incredibly joyous, beautiful at times and gross at others, just goes to show how many different uses there are for Water Melons!
Thanks guys, great film for the more broad minded and those who like their films crammed full of metaphores.
