today re-watched this blu-ray,with the foll sound settings on my Onkyo-606 amp:
1) turn equalizer settings off
2) reduce the surround vol to min
3) watch the movie in Dolby digital & not DTS-HD(HD audio seems to've been extracted from DD track,as DD track is much more punchier.same was the case with Jodha akbar)
4) most importantly,all the onkyo amps have a "Late night" feature,which shuld be set to LOW to reduce the sharpness of audio.

the above settings did some what reduce the harshness of the surround effects but not completely.
eg..the shootout after the Latoo song in the parking lot,still sounds very harsh.

bottomline:this BD's audio mixing is very poor,DVD still sounds good!!

the sound in bd despite of these issues is not poor in anyways ill still give it 4-4.25/5
