The story starts right from the word ‘Go!’. Bala played by (GV Prakash Kumar) comes out of a police station and seems very nervous about something. As he is striding on his bike thinking about gathering money to pay back his loan, he stumbles upon a big villa. Once he hears that everyone from that house is not in town that night, he decides to rob the house. When he climbs the villa’s compound wall and jumps on the other side, his fall is deep. The task and the wall seemed possible at first but then just as Bala, we fall into something deeper. Bala’s multiple attempts to somehow break into the villa without causing a scene gets him face to face with Bruno, the dog. Finally, after failed attempts to escape Bruno, he gains courage and gets into the villa.
GV Prakash as an actor and music director has exerted his efforts to carry the film on shoulder. Nothing to blame upon him for he had done what the role requires. Suman and others in the star-cast have done their portions well. The golden retriever Bruno will surely become the favourite of kids in theatres. The laziness keeps prevailing throughout the film, except for the few penultimate-to-climax portions. Director Vijay’s screenwriting lacks the punch that ‘Thrillers’ demand and Watchman runs short off what it should actually possess.
