Direction and other technical details are good. This story is a must-told one for today's audience. The screenplay could have been better. The writing had many red herrings, overlooking basic elements like drug dosage, unclear explanation that convicts are 'five' in number etc.,. A worthy urban investigation that fell into a compulsive twist factor, perhaps to meet 'hero-ine' status (just like Aramm ending or so). I'd compare the project to Manikandan's Kuttramey Thandanai for its simplicity and technical greatness.
