Don is slick and well conceived on plot with lots of surprises along the way. When I was trying to work out originally whether this one was for me I wasnt sure how serious it was or whether it was a light Bollywood. For those who have the same question in mind - it isnt really light overall.
Don is an arrogant psychopath drug trafficker - and I'm afraid, unlike other Bollywoods, good doesnt win in the end and the nasties dont meet their consequences. This may not particularly bother you or you may like endings that arent politically correct. For those not in that category be aware that the surprise ending actually left me and my adult daughter feeling quite uncomfortable and gave us a restless nights sleep after. Those we had identitified with dont triumph (sorry about the spoiler but you may need to know that if you want to assess whether this is for you).
I have given it a 5 because of its quality but a different ending would have made me more excited about this movie.
Given the amoral ending its fascinating that Indians wanted to do this movie twice (it is a remake of an earlier celebrated one) and seem to love the character of Don.
The music was fine but none of it stayed with me or stood out. A few of the dance sequences were good so there was song and dance amongst the plot (something I also wasnt sure of when reading prior reviews).
