Lovely Star Prem sheds his chocolate-hero image and tries his hand at action for the first time. The effort is commendable and showcases a little-known (or seen?) aspect of his on-screen skills. Having said that, the film does lack freshness and is riddled with cliches.
The story is old wine in new bottle. It almost resembles Kempegowda where police officer Kempegowda takes revenge on Armuga, a rowdy, but in Shathru our hero Vijay Surya takes revenge on Adishesha, again an influential person in a city, who will be running a parallel government with his henchmen.
