With all it's twists and turns, Don 2 marks a decent end to the year for Bollywood. The movie's strengths are action, plot twists and it's faced paced storyline which always keeps you at the edge of your seat.
Yes Don 2, does borrow from some Hollywood flicks like Mission Impossible, but it's neatly made and the plot fits in like a jigsaw puzzle at the end of the movie.
The only negatives were the touch of grey given to Don's character and the love story angle towards the end. A completely cold hearted Don, who's way beyond meaningless things such as love would have been more appreciated. The character could have been made much darker, which would have appealed more to the audience, but then again it's a Hindi flick, so such things are expected.
There are a few holes in the plot, but after all it's a Bollywood flick and no one expects it to be perfect.
I would say Don 2 is a decent one time watch and do watch it at the theaters as the cinematography is brilliant.
