We should just let the little one's in us rule the world.".^[25] Subhash K Jha of Indicine gave the movie 3/5 stars, saying that "Gattu carries forward the recent trend of sensible, intelligent funny and moving films about child protagonists, namely Taare Zameen Par, I Am Kalam and Stanley Ka Dabba.
