I think one shud stick to ones comfort ..there are movies made on all topics these days but not necessary that all wud be blockbusters..I think its really hard to satisfy the taste of each audience and as a result one shud stick to wat he is comfortable doing...u don't wanna mess it up and look stupid at the end of it...unless u really wanna look stupid.....So he needs to b wat he is why change...If u have a loook at all the names of the movies he has directed all were superhits...so why change unless things not going rite??????
