Slightly OT: The Tragedy of Macbeth

An increase in laminar flow the opposite of a box of foam. Laminar tubes capture air flow at one end and direct that air out the other overcoming boundary interference.. and will help to unravel words hidden in a box sitting on a shelf. You are smart, drop the software and look around and be creative. Tom

I didn’t have any issues hearing the dialog. Perhaps due to my center channel being concentric? (Elac Adante)  I believe the actors were speaking in iambic pentameter. What was interesting was the choice of aspect ratio.
We didn’t finish the movie, but may return to it.

I read an article a few months ago that asked if you are having a problem hearing movie dialog? But not so much "hearing" it as being able to distinguish the words. Apparently it has a lot to do with the sound production at the time the movie is made. This is a pervasive problem and there is not much we can do about it. If you saw saliva emitting from the actors mouths then you know they are using proper volume and diction with the Bard’s work.

Judging by the trailers, the principal emphasis is on the moody B&W look and other atmospheric film noir details, of which the sotto voce dialogue would be a part.

For contrast, try Kenneth Branagh's filmed version of a stage performance of Macbeth, from 2013.

Even better, for the ultimate Shakespeare movie experience, try Branagh's Henry V. Be sure to play it through a quality audio system or home theatre, as it has an excellent originally composed score that runs throughout.

It also bears saying that some actors train for half a lifetime to perform Shakespeare, so being a successful screen actor isn't a guarantee of equally successful "crossover" success.
