Initially i was more excited for Dhoom 2,as Hrithik looked Uber cool,and Ash gorgeous.....The first trailor of Don wasnt too convincing,whereas the first trailor of Dhoom 2 was smashing..But I guess Don has a fabulous storyline,and It would be really interesting to watch SRK play the frivolous and amusing Vijay..But If I have to zero in on one,It would be Dhoom 2,As it has Abhi ,Bipasha(who too looks exceptional),Ash and hrithik..and Uday Chopra would be good as the fun loving Ali....Thus,its dhoom 2
But look at the plus side...they arent releasing on the same day,thus one can enjoy both thoroughly😛
