Bollywood is a formula repeating industry and it doesn't generally go outside of the narrow and defined path. They never think out of the box. If you look at world cinema some of the most repressed and war torn countries have come out with outstanding movies - Iran, Yugoslavia, Poland, and even Pakistan. But we are stuck witht he usual song and dance routine.
The song and dance was fine when we started in the early part of last century and it was primarily used to entertain new audiences and it made sense as it was easier to convey a message with a long of dramatics. But as other cinema's progressed we remained in teh 1940's and continued using songs and dances to convey emotions and feelings. It is also a unique and distinctive asset but we shud also innovatie - especally as cinema is a medium to tell a story.
Abraod animation has reached amazing levels with it spawing an entire industry in itself and the super hero segment is also very popular with every year some masked crusader throwing his hat in the ring. Bollywood has only a Koi Mil Gaya, Krrish and perhaps a Shahenshah to show for its efforts. It helped that Krrish did well and it assured producers if the movie is well made it can do well.
Next on the anvil is the super hero seeped in mythology, the film Drona. The story strongly reminds me as a mish mash of Da Vinci code and Mummy, with Priyanka playing the head of a cult that protects the main character Abhishek from his enemies.
