Without using headphones, without turning the volume up - I don't hear it want the experience to be as close to natural as possible.
Maybe it's because I do not hear f..k used commonly, that it still has a minimal shock effect on me, and don't get that. My family does not say it, my friends do not say it. my coworkers do not say it - so...
For the same reason, do not stop, reverse, ff or slo mo the film...
If something was to be noticed in the film, think that it would be evident at "normal" viewing conditions.
