This is probably the best way to educate the majority of India regarding homosexuality.
Even very serious scenes are made in a fun way. The people who gave negative reviews probably didn't get director's intentions. He meant movie to be silly. But still it has something important to say.
Another thing I loved was the portrayal of gay characters. They don't have any stereotypical mannerisms of gays. It's funny but it doesn't make any gay jokes.
And using the iconic scene from DDLJ was brilliant. We always get to see a man and woman in love. But we never got to see a man and man in love or a woman and woman in love.
This is a really fun movie to watch. I didn't expect much and maybe that's why I enjoyed it so much.
