Reviewers say 'Gullak' is acclaimed for its authentic depiction of middle-class Indian family life, highlighting relatable moments and emotions. Strong performances by Jameel Khan and Geetanjali Kulkarni, along with organic character chemistry, are celebrated. Witty, heartwarming, and poignant dialogues balance humor and drama effectively. Cinematography and music enhance the narrative's emotional impact. Themes of familial bonds, societal expectations, and personal aspirations resonate deeply. Minor critiques include political undertones and costume inaccuracies, though these do not significantly impact the overall positive reception.
