My review is purely based on my perspective as an audience. I do read good stories as well.
1. This character of Shoku by Satyajit Ray has a nostalgic value for most of Bengali children of the 80s and 90s. Portraying him with mobile phones and laptops doesn't really strike the right cord.
2. Using VfX should be logical and shouldn't be used unnecessarily. Like there is a scene where Shonku dials or saves number from a holographic gadget. Why? If you have more convenient mobile phone. The teleconference by a holographic projector seemed unconvincing. It would have been better if all the guys were sitting as normal instead of floating over the table. Eg. In Avenger movies.
3. The screenplay was so boring that I had to fast forward a lot. The scenes of people travelling were... of only them travelling and driving, nothing else.
4. The story should have taken place in the 80s.
5. The acting all around was mediocre. Seemed like the casting director had hired some foreign tourists with elementary acting skills.
6. Only good part is the effort put in and indeed the professionals behind the camera have worked hard but the whole thing fell apart due to poor conceptualizing and screenplay.
