The movie is like a smoothie of Mahabharata and Hollywood movies( dooms day movies). Casting is interesting. Characters blend well. Everything connects to a single event. Other characters explain why the mother character is important. Basically you know the gist of the story. If you know Mahabharata. The character raia is 'us'. Our questions were answered by the questions of raia. I think 2nd part will be more interesting.
