Love the characters but the turn is bad

Rating: 6/10 (22 March 2014)

Sue finds her grandfather's journal of his days as a prison guard in colonial India. She wants to make a film about it, but the film company doesn't want to. She goes to India to meet up with a friend who introduces her to a bunch of University friends. They're all fun loving and aimless. She makes the movie using them. At first, they don't understand the commitment and the drive of the characters. Eventually the film influences them all. However the death of someone special ignites a dangerous fire in them all.
I'm not much into Bollywood, but I figure I check out this highly rated movie. I do like the first half very much. I could do without the song and dance. However I love all the characters and their struggle to find purpose in their superficial lives. I could even gloss over the song and dance breaks.
Then there is a big turn midway. While I understand the reason for the turn, it's highly overdone and too big. It takes the guys down a wrong path. If there is a good message in this movie, it is compromised by the second half.
