Why EENADU failed at box office?

Kamal haasan should have lifted the exact script and dialouges to make it hit , but unfortunately he changed some dialouges and he was delivering dialogues at the end with sad note and there are some funny dialogues in the movie, he should have been delivered the dialogues with anger, terror and frustration as naseerundin shah delivered it ,when common man went on such a daring act he should not be sad, kamal haasan missed this one and he cried in the end scene with different dialogues,the terror element and terror music is missing in the movie for which the movie bombed at box office !No doubt kamal haasan is the greatest actor ever in indian history but When we are remaking a classic movie we should not change the essence of the film and dialogues this is basic thing , which lacked in director !! venkatesh had done a decent job !!
