Uncomfortable, grueling, slow, brooding near masterpiece!

Rating: 8/10 (4 October 2019)

While it would have benefited from about 15 minutes of additional judicious editing, and has a tonal misstep at a critical moment in the final act, this is still a courageous must watch film for anyone that found the trailer compelling.
If you're wanting an action film, you'll be disappointed.
If you're a big DCEU fan you'll likely be disappointed.
That said this dark, plodding, disturbing, character study fully delivers on the grisly promise laid out in the trailer.
Phoenix is guaranteed an Oscar nomination, and deservedly so. Easily the most daring DC comic adaptation to date.
Definitely not a crowd pleaser or easy watch, and a better fit for fans of Lars Von Trier, Yorgos Lanthimos, and Ari Aster than those of Zach Snyder and the DCEU.
If the above gives you pause, you've been warned. If it actually makes you more piqued then this entirely singular entry in the genre will deliver in spades,
