Gulu Gulu is a Tamil black comedy written and directed by Rathna Kumar. It has Santhanam, Mariyam George, Pradeep Rawat forming the cast of the film. Circle Box Entertainment produced the film while Red Giant movies bagged the distribution rights.

Google (Santhanam), an outcast, lends his heart and hand for those in need of help and gets himself caught in an eccentric situation.

Santhanam as Google is convincing right from the word go. These are the kind of roles he needed badly. He has finally pulled out the rabbit from his hat which was long due. This Santhanam will be different to people who expect the regular counters from him. Mariyam George and his gang, the PUBG gang, the friends gang score regularly with their peculiar attributes. Pradeep Rawat playing the typical untypical villain makes us hooked to the story. Every character inside the film serves their purpose well. Even a rejected bridegroom and a small school girl is used accordingly.

The selling point of the film would definitely be its quirky one liners, strange situations, writing of Rathna Kumar and the innocence of Google. SaNa scores his part just as he does in every other film. Watch out for the song Anbarey which works very well in tandem with the visuals. The film is non stop in kindling laughter every now and then. It also addresses certain themes that are overlooked in the society including extinction of languages, trauma of Srilankan people, and more importantly the purpose of living.

The writing of Rathna needs to be lauded for the insinuation of darker themes in an otherwise usual screwball comedy. It also should be doctored to cloud the lagging moments in the film. Dialogues are the pillars of Gulu Gulu which makes us laugh as well as contemplate. The film brings out the hero in Santhanam through its brilliant writing. We rise and shout for the cinematic mass moments of our protagonist.

The strength of the film lies in the manifestation of the script onto the screen. Every technical department has contributed to the flawless creation of Gulu Gulu's world. Vijay Karthik Kannan captures what is necessary for the film and outsmarts the script while portraying sensational scenes. SaNa is SaNa in background score which proliferates every feeling that is to be sparked. The good editing by Philomin Raj compliments the writing of the film. 

The script moves in different directions which breaks the engagement factor. The second half takes its time to settle which then is brought back by Anbarey song. The film satirizes many pop culture references to invoke laughter which may work only if you know its background. The film is far-fetched at times as it asks us to buy too many things swiftly.

As a whole, the film works very well in delivering its essential core while trying to break conventions. It makes you laugh, laugh and cry when handling issues and laugh, laugh, and laugh when plans collide. This film guarantees a wholesome entertainment for those who don't question the contrived situations.
