OK Kanmani completely depends on the lead pair and boy haven't they delivered? Nithya Menon deserves a pat on her back as she can even emote emptiness while carrying a grin on her face.
Dulquer Salmaan has managed to perfect his Tamil accent and his expressions too are apt for the role he's been asked to portray. Prakash Raj saves a sluggish first half and Leela Samson playing his wife, has done justice to her character as an Alzheimer patient.
Overall View: The film can be called as a prequel of Alaipayuthey with all the elements required to entertain today's young movie goers. OK Kanmani is more than just OK.
