Probably, this is the best movie sequel ever produced in the Hindi cinema and surely would be one of the top ten comedy Hindi movies of all times. I can't remember if any comedy movie (hindi or other) ever been able to deliver such a strong message in such a subtle and non-preachy manner. Coming out of the cinema hall, you can't help from having that huge delightful smile on your face.. This movie isn't a sequel in its true sense; apart from the characters of Munnabhai and Circuit, there is nothing in common with its predecessor (unarguably, the movie would not have been possible without these two characters as in their original form).
Few reasons which turn it to a must watch movie:
1) awesome movie, with astounding screenplay, story, characterization and many other things. Its a 100% clean movie with no risqué dialogues, no item number, no vulgar dresses and no vulgar scenes, which is an achievement in today's times.
2) Performance of Munnabhai and Circuit duo - Sanjay dutt is undoubtedly the most lovable bollywood bhai, he is bit old now but still going very strong and Circuit has come up with his magic yet again, this guy's timing of dialogues is perfect... In all, the duo rocks!!!!!!!
3) Strong, strong and very strong message delivered... I won't delve much onto this or else risk disclosing the story and henceforth the fun... Everybody is going to respect Mahatma even more after watching this movie - bet you are going to love that enigmatic smile
4) Jhanavi (Vidya Balan)... such a graceful beauty, her face is like bright morning light; gosh, the lady literally smiles with her eyes, you are bound to fall in love with this gurl, just like Munnabhai.. apart from that she acts very well and gives a strong performance...
There are many more things that make this movie memorable and a treat to watch.... surely, something to watch before you die :-)
