The humour here isn't slapstick but silly and kiddish, having said that it's innocent. With songs and action, the first half is energetic and has lesser flaws than compared to the second half which has too many characters to spoil the flow. The characterisation of a don Anupam Kher and his assistant Saurabh Shukla are expectedly and intentionally made comical but they don't contribute much to escalate the fun.
Whenever, they play spoilsport, Varun comes in jumping and showing his comical shades. In the end, it's his efforts, which are a big time savior of this drama. At times you feel, if it wouldn't have been him, then only big stars like Salman and Shah Rukh would have been an appropriate choice for this masala entertainer, which is like a drowning ship battling hard in high tides.
Varun carries the entire drama on his shoulders and undoubtedly he is a package of talent and energy. His lively act and fun dialogue delivery livens up the screen. His dance encourages you to join him at every step.
