Bollywood

So, I have a question then. I have watched very little of Bollywood. Its not exactly in stock at Blockbuster. Of what I have watched, it didn't really want to make me want to watch more of it. I think I watch parts from Sholay and Laagan. Sholay seemed a little cheesy, kind of like Lethal Weapon meets John Wayne meets Oklahoma!. But I also watched Laagan and I liked that a lot better, maybe it just reminded me more of straight up Musical Theatre. Anyway, what do you think are some of the things that set Bollywood apart from American Musical films, and also how do you differenciate between Bollywood films as being either good or bad in your opinion?
