Ratsasan is a mash up of what would happen if you replaced Clarice Starling in "Silence of the Lambs" with serious version of Abid from the TV series "Community". Protagonist Vishnu uses the knowledge and skills he acquired from his failed film career to hunt a serial killer.

The film has plenty to commend it except for several major sins repeated throughout:

1. Plot Driven By Stupidity - Every 15 minutes you are shouting at the screen "Why are you doing that stupid thing???" Vishnu learned some things from watching films, but obviously didn't learn many tropes like not calling for backup.

2. Predictability - The second a new character even appears on screen, it is patently obvious what their role will be.

3. Lingering Direction - The film would be much snappier and flow better if it didn't linger so much on many scene moments.
