Kooman is a testament to Jeethu Joseph's skill in crafting seat-edge thrillers. It also extracts an insanely good performance from Asif Ali - playing a fairly intelligent cop named Giri, who also decides to embark on a series of burglaries as a means to get back at his superior officer. The first half shows his ruthlessness at exacting revenge on people who shame or ridicule him at the slightest, and Asif's subtle expression changes during these stretches are fantastic to watch. The screenplay (by KR Krishna Kumar) is also good at tapping into the vulnerable side of a steadfast policeman, and we as viewers are driven to get behind his criminal choices.
In Kooman, we actually get two films instead of one - it's a tale of two halves. While the first focuses on his nightly shenanigans which itself keeps you interested, it further dives into a series of murders happening in the area, and Giri finds himself tied to one of them in unexpected ways. Giri's obsession with robbing people just for kicks is what gets him embroiled in this issue. The film then moves ahead from its initial central conflict and starts to revolve around Giri's unofficial investigation on finding the murderer. If not for the recent events that unfolded in Kerala, the climax would have come across as rather absurd and unbelievable in this day and age. But kudos to the writer and director in their ability to prophesize a ghastly incident, and for executing it in a sufficiently thrilling way.
The villain reveal (and the extended climax) do not fetch any points, mostly since it became rather obvious in the scenes preceding it. The action set-piece is also pretty tame, and the mere mention of a character's queerness (as an excuse for villainy) takes away ½ a star. All said and done, I'll recommend the appropriately-titled Kooman to those who relish thrillers. Special mention to Jaffer Idukki for his wicked performance as a semi-retired thief, especially in that scene where he elucidates the "high" he gets from thieving. Vishnu Shyam's score is also top-notch. Give Asif Ali more such roles, please!
