I don't know much about it. I've heard that they get ridiculous sometimes with the dancing. I wouldn't know.
Before, I thought that one of my favourite movies, Slumdog Millionaire, was made there, but I read later that it's a British film. There is also Lucia, which I thought was made in Bollywood too, but it's not either. So it turns out that even though I thought I was watching Bollywood movies, I really wasn't, so I would say that Bollywood hasn't ever touched my life.
