Umapathi then calls his friend and narrates to him the entire incident. His friend instructs Umapathi to leave the pace and not get involved in any trouble. However, he forgets his guitar there and goes back to collect it. However, he doesn't find it there. He assumes that the police might have taken it since it had a note with all his personal details and begins to fear for the worst. The next day he heads to his best friend Karunakaran and tells him everything that had happened. That is when they come upon the news that a bunch of robbers had stolen from a rich family with guitars in their hands. He then decides to find the robbers before the police with the help of Karunakaran. Whether the fearful Karunakaran manages to help his friend out of this mess forms the rest of the plot of this film.
Thambi Ramaiah's son Umapathi will surely live up to his father's name and he shines in his role of looking innocent as well as in the comedy scenes. He even makes an impression in his dance and is surely a good addition to Tamil cinema. Actress Reshma Rathore as the heroine is okay in her performance while Pandiarajan as the hero's father has not much screen space for a performance, but does a decent job. Aadukalam Naren plays the role of the industrialist and this is a different role for the actor, who is more often seen taking up serious roles. Manobala's character is the surprise element in the story as he delivers a big twist. Karunakaran can said to be the second hero of the film and he comes throughout the narrative. Be it in scenes where he gets trapped and beaten or the ones he comes off on top, he leaves the audiences in splits. Thambi Ramaiah makes a came o and plays his part in a satisfactory manner.
Director Inbasekhar has made a jolly entertainer and has struck half of the success with the film's casting alone. He has made a film that can be watched with the family. Had he made the runtime a bit short, the film could have benefited a lot more. PS Varma's cinematography skills come to the fore and he has made the film look lively and colorful. D. Imman's music adds good strength and the same can be said about his background score too.
In short, Adhagappattathu Magajanangalay is a fun watch.
