This is a character was once played by none other than Sri Uttam Kumar , excuse me, Mahanayak Uttam Kumar, in the portrayal of Bombkyesh Bakshi.
The film adheres the audience till the last, was extremely good in maintaining the thrill, however there could have been more charisma and connectivity of the clues during the plots.
I just stated this because any criticism or review you need assess the bar high performances set by the stalwarts to the current genres of film.
This film comes nowhere near to that of course. However, having said that this film was watchable due to the presence of supporting actors like Mr. Mukherjee and Mr.dutta.
Now let's discuss about the film's loopholes, Dev's dialogues in this movie despite being a protagonist and the main character are lesser, Dev is a rom com actor, and it could be felt the romance with Rukmini. He is truly a romantic actor here.
Dialogues were rough and raunchy, given the timeliness, the throw of the dialogues within the Royal family was like local "parar" chele kind of a throw!
