Finally got around to seeing this, what, almost a year later from posting this.
As someone who hasn't read MacBeth in around 7-8 years but has watched recent adaptions, the story was very familiar (seriously disappointed in the posts on here who had never read or watched a MacBeth play or adaption, you uneducated rubes), but I think the minimalist set pieces and the black and white lighting/shooting made it feel unfamiliar.
There was definitely a gothic feel and at first I wasn't thrilled with Denzel's portrayal, but by mid-film and once he started to fall into insanity, I think he found his gait and he nailed the iconic lines and carried the film to the end. I was pleasantly surprised with MacDuff too, I thought he nailed the part and beyond Denzel comported himself the best.
Not sure where all the FMcD love is coming from-- very average performance IMO. Not bad, just nothing special. I wonder if her reputation precedes her in this case, but I've seen better Lady MacBeth's in suburban community theatres. Not really, but you get my point.
I really enjoyed the portrayal of the witches-- that lady was probably the real MVP, actually.
Anyways, 8.5/10, a pretty faithful adaption of Shakespeare (though never in love with Ross being the Third Murderer, it's never made a lot of sense and Coen does it here), with a cool take on the minimalist set design and black/white.
Unlike Bloom, I think this was better than my quoted post above which he (as a renowned Shakespeare and Western canon critic) said was the best adaption of MacBeth. It sucks he passed before this was released I'd love to have heard his take.
