the only good thing about Dhoom 3 was Amir Khan, the guy delivered and did justice to his role, the story was inspired by Prestige, The Illutionist and Now You See Me with lot of loop holes and at times pathetic execution.
Katrina was used as a condom i.e. used for ejaculation and thrown away, why she opted for this role is beyond me (i guess she got paid a lot or is desperate enough).
The locations and some camera work is very good, they managed to execute few matrix inspired shots in a very very nice way so kudos on that, but again there are times when we come back to our desi roots and executive sultan rahi type action sequences which just leaves you in a WTF mood.
I am so happy that i didn't had to pay to see the movie else would had felt so bad about wasting money (perks of being in cinema industry).
Edit: It makes me so happy that few of our Indian members are comparing a movie with star cast of Aamir Khan, Katrina and Abishek backed behind a strong established brand name "Dhoom" to a new venture with relatively unknown cast and people, thank you guys for the moral boast
