Guptodhoner Sondhane is one of the good examples of horror adventure mystery which stops itself from falling in the pit of cliche. Blend of genre is in proportionate portions but it could be a drawback as well because it does not serve any genre to the fullest. Apart from being set in an old fort, it is also shot mostly in bright light to give a newness to the thrill of fear. It is more like a scary treasure hunt which is very intriguing step by step and gets difficult after each level.
Screenplay of the film is quite clever because it keeps the viewers with the characters by not giving more or less information about the plot. Audience would get aware of the facts with the characters in real time like a detective story which is certainly in the blood of Bengalis. Readability of the situation would change perspectives as each character grabs more hold on the story with every passing minute of the film. narrative would also change the favorites in accordance of the contradiction to antagonist. As someone would become the hero, others would look like menace to everybody.
It was a Shakespearean flaw in the narrative to not make any character a protagonist hence the doubt revolves on each of them till an actual villain walks in the film. With the arrival of antagonist, the film starts to dull down and eventually forgets to live up to the potential. it could have been a landmark film especially in this kind of the budget but gets itself trapped into the mediocre norms of storytelling in Indian cinema which reflects poorly on the makers. Cast has done a good job playing those roles and shall continue to if they make it a franchise with better writing. Overall this can be seen in cinema if intrigues.
