Effective writing makes this investigative thriller a compelling watch.... Sarathkumar & Ashok Selvan performance top notch.... Specifically Negative Character Vera Level.... (Find out who is in the Movie)... Background score is even more terrifying.... Debutant director Vignesh Raja has pulled off a phenomenal job with 'Por Thozhil', making the minor mishaps almost feel like a product of nitpicking.. Por Thozhil is not just a film that works through technical qualities and the performances of the cast, it is the writing here that clicks. Working with Alfred Prakash who is the co-writer, director Vignesh Raja has managed to present a film that is as compelling as it can be for the entirety of its runtime. Must Watch Film.
