Definitely worth the watch....i was reluctant to watch it since some of the reviews were quite bad, but the Mrs is a big John fan, so had to watch it and I actually didn't at any time get distracted and felt the need to play on my iPhone or anything. It is certainly much better than some of the asinine movies coming out of Bollywood ( here looking at you Akshay Kumar who makes way too many movies and whose last few movies were barely watchable,oh god , Khatha Metha made me feel like killing myself for wasting 2 hrs of my life!).
John does a good job ( much better than I would have expected and the director has been smart by having a good ensemble built up around him of actors who complement him and keep the momentum going. Only negative is that the script could have probably done with a little more tweaking, but nevertheless a good effort and something different from Bollywood. Would definitely recommend this....
