Namrata Joshi reviewed the film in Screen International and wrote, "Amar Colony is an original blend of the sacred and the profane, the sensual and the spiritual, and the real, mythological, surreal and the bizarre.

A delicate, rich and unique portrait of an exotic community that in fact represents all of us.".^[60] Saibal Chatterjee reviewed the film for NDTV and gave it 4 out of 5 stars, calling it a "a meticulously crafted, hypnotic film that is firm in a deliberate rhythm...Amar Colony heralds the advent of a filmmaker endowed with the ability to see beyond the surface of things and illuminate what lies beneath.^[61]
