Ambitious, but poorly executed. Set backs of having serialised the novel in a weekly. The chapters and characters are loosely packed, the narrative is inconsistent / unconvincing and at times stupid, too much of unnecessary information fillers about Tamil and its ancestry, bland character inclusions from Obama to Rajini to Anjelina Jolie to Brad pitt to bill gates, dumb antagonist.
I wish people actually write a novel when they take up a sci fi subject instead doing all the above blandly. First & foremost you need to stop serialising it - which is main reason behind inconsistent narrative.
To be penned by Tamilmagan who actually wrote something extraordinary like "Vettupuli" is unbelievable. If only he had done the same thing he did with Vettupuli, this would have been a good entry in tamil commercial fiction.
