In the meantime, Rathan helps his friend get married to the woman he is in love with. Since his friend is from another caste, this irks the girl's father and he brings to light the issue to Rathan's father. However, Rathan's father is a progressive person and says that Rathan has done nothing wrong and this leads to an enmity between Rathan's father and the girl's father. Rajasimha, who already has sworn to kill Rathan's father teams up with the girl's father to finish both the father and son. In the meantime, marriage preparations have begun at Rathan's home when Nayana's mother comes across a particular photograph after which she decides to call off her daughter's wedding.
In the second half, Arasakulam then proceeds to address who the person in the photograph is; why Nayana's mother decided to call off her daughter's wedding and whether Rathan and his father evade Rajasimha's plan to kill them.
Rathan Mouli is energetic in all the scenes he appears in the film, but needs to work on getting the expressions in the romance and action sequences right. Heroine Nayana Nair tries her best to perform and comes off achieving it partially. Rathan's father in the film has done his role justice and stands out in all the scenes he appears. Rajashree has once again brought her experience into play for this role too. Rajasimha has done a decent job as the villain.
It is unknown who director Kumar Maran wants to impress with this film. Rather than pinpointing the mistakes of the actors, the script and screenplay need to be criticized. The actors in the film have acted out the instructions given to them by the director. However, the filmmaker loses track of what he intends to tell. Cinematographer S. Chandrashekar has made the film as can be made on a restricted budget. The background score too is just ordinary. The director has not utilized what has been offered to him.
In short, Arasakulam is an experience at your own risk.
