I want to start the review by appreciating Sandip Ray and team for venturing into the audacious task of bringing Professor Shanku from pages into the screen. The biggest challenge in filming Shanku is the necessity for advanced graphics and exotic location shoot. While camera work in the streets of Sao Paolo and bird's eye views of the amazon rain forest catches attention, the VFX team has done a mediocre job at best. Acting through out the film has been reasonably good from the Indian actors. Dhritiman as Professor Shanku seems unnecessarily annoyed at times but overall has portrayed the character well. Subhashis Chakraborty fits in the role of Nakur babu perfectly too. However, the foreign actors in the roles of Dr. Sauders and Krol are too expressive, even tiring at times. The use of music in the film is commendable, enhances the cinematic experience. Sandip Ray has not veered far off from the Satyajit Ray school of music, the tunes in the movie sometimes reminded me of the Feluda theme. However, the main issue with the movie to me is it fails to hold your attention. There is no build-up of suspense, no sequence for provoking thought in the audience; It's more like a grand Brazilian travelogue. I would like to see more audience engagements in the upcoming Shanku ventures.
