Just don't bother, it's a farcical exercise, as you will soon realize. Better, go for a walk and forget this horrible experience as a bad dream!"^[1] Paresh C Palicha from Rediff.com wrote "Jayasurya after doing a couple of intense roles in the past few months returns to doing senseless comedy. Radha Varma has nothing special to offer and is mediocre to say the least. That leaves the comedians led by Jagathy Sreekumar, Suraj Venjaramoodu, Anoop Chandran, Bijukuttan and others to entertain us, which they fail to do due to lack of cohesiveness and purpose. In final analysis, Doctor Patient drives viewers crazy"^[2]
