Although Detective Byomkesh Bakshy! works hard on creating a convincing setting for Byomkesh to make his mark, the characters are mostly under-written and the central mystery lacks tension and a sense of imminent danger.

Despite all its flaws, I would still say that DBB’s ambition, scope, and attention to detail are reasons enough to watch the film. But by the end, it seems evident that the film is far too aware of its own coolth and is more interested in using it as a smokescreen than as a welcome embellishment.

Don’t miss it. Even if just to go back to the magical world of nostalgia created so beautifully and earnestly by Banerjee and cinematographer Nikos Andritsakis.

For all the beautiful production design, the clever use of contemporary indie music as the soundtrack, and the stylish cinematography, Detective Byomkesh Bakshy is Banerjee’s most underwhelming film so far.
