Parole's script is by Ajith Poojappura. The story of the film isn't anything new and there are some striking similarities from some of the films of the past.
Siddique essays a character named Abdu in the film and as usual he does his role to perfection. Suraj gets to play the role of Varghese and he has done a good job.
Verdict Parole has its moments, especially in the form of Mammootty's soul-stirring performance as Sakhavu Alex.
