Blake Petit’s review published on Letterboxd :
2018 Superhero Rewatch adjacent.
DC's second attempt at animating the Death of Superman storyline is a home run. Adapting the story to fit the characters as they exist in the Post-Flashpoint DC Animated Universe isn't hard, and adds somewhat more poignancy. As much as I loved the original storyline, seeing Doomsday throwing down with Wonder Woman and the Flash makes him seem a lot more menacing than Blue Beetle or Booster Gold. The film doesn't rush through the story either -- it's paced nicely and ends on a dandy cliffhanger. Even the slower beats from the comic, such as Bibbo Bibbowski's recitation of a Hail Mary, carries a strong emotional punch.
And Rainn Wilson as Lex Luthor? Assistant to the Legion of Doom no more. He rocks.
