This film doesn't suck
I'm sorry, but it doesn't. It can't. Maybe I am too soft, but besides vapid tripe like The Room or Birdemic 2, I will always hesitate to uniformly pan a movie, because there is often so much to like.
And in this version of Macbeth it's no different. Look at the incredible cast they assembled. A dream team of amazing talent, and even those who don't appear often, like David Thewlis, really give it their all. And can we talk about the costumes and the set design? Maybe I'm alone, but I loathe modern retellings of the story, and always think it should be fixed in Dark Ages Scotland where it began - a time of Knights and codes of chivlary and uncharted wilderness, where people really did believe dark spectres lurked. Everything from the castle, to the coronation robes is so beautifully rendered.
In terms of core elements, there is so much to like about this movie.
But the problem is that, in a sense, they didn't find the right balance. If you overstate the text, you get something akin to Kenneth Brannagh's 2013 staging of the play, which, though I like Brannagh, is bloody awful. People scream their lines, and there's no nuance to it at all. But fail to find the emotion in the text, and even actors like Fassbender can't save it.
His Macbeth does not fail because of him, but because of the theme of the film. He is portrayed as a broken man, compensating for a lost child and his own demons conjured up by PTSD. And to go down that road takes away the key theme of the play: hubris.
So, rather than see Macbeth become an arrogant tyrant, confident and secure in prophecy and his own suffocating sense of invincibility, Fassbender's version starts as a broken man and ends that way - muttering and mumbling, a very clear victim rather than villain.
I applaud them for this different take on the text. But it doesn't make for enjoyable viewing, because we don't get to see his power lust, we don't get to see him enjoy power and play the King, because his Macbeth barely seems to want the crown at all, he's more dead than alive.
