Known for his comedic timing, Munishkanth takes on a more grounded, emotional role here. While he brings a natural vulnerability to the character, critics noted that he sometimes appears "clueless" in the later episodes due to a lack of clear character direction in the script.

Postman starts as a promising "what if" story packed with Rajinikanth references, but it ultimately struggles to maintain its momentum over 10 episodes. It is worth a watch for die-hard fans of the lead actors or those looking for a light, nostalgia-driven anthology, but it fails to deliver the deep emotional resonance its premise suggests.

Despite its heartwarming premise, Postman received from critics:

The narrative begins on the day of the release of Rajinikanth's iconic film Baasha . (Munishkanth), a local postman and die-hard "Superstar" fan, is so preoccupied with the movie that he neglects to deliver nine final letters. On his way home, he meets with a life-altering accident and slips into a 23-year coma .

The first two episodes are widely considered the strongest, effectively capturing the 90s nostalgia and the emotional weight of Raja's awakening. The cinematography in these period portions was also a highlight.
