if by interesting you mean "nauseatingly drawn out and boring with cheesy camera gimmicks and piss poor direction", and if by stylish you mean "just another installment in an already mastered genre by ritchie/tarantino fanboys with a $50 screenplay" -- then yes, it was interesting and stylish
Think of it this way: If KK were say, rosie (who could probably use her barehands to whip the sh!t out of twenty keiras with automatic weapons), would you call the movie "interesting and stylish"? You couldn't pay me to watch that garbage a second time.
There you go again, resurrecting ancient threads
