A two-hour, live-action 'Justice League Unlimited' episode

Rating: 9/10 (26 November 2017)

The most fitting synopsis I've seen to date is that this is a live-action, two-hour long episode of Justice League Unlimited (the Cartoon Network show). If that's your thing, welcome! :)
The casting is near-perfect. Gadot, Cavill, and Affleck already have proved themselves as their comic book counterparts. But Momoa, Miller, and Fisher go the extra mile. The Flash is lighthearted enough to remind us of Wally West, but illustrate an extremely young Flash who isn't even a cop yet. Miller gloriously captures the brooding and conflicted young man who wanted to die, and resents his father's decisions while still caring about him. Momoa's Aquaman has phenomenal potential, clearly drawing from the late 90s to mid 2000s gruff, vigilante-style Aquaman. But Momoa keeps both hands.
The CGI is no more gratuitous than any fandom-based, big-budget film that relies largely on sci-fi/fantasy elements (looking at you, Pacific Rim, Hobbit Trilogy, Marvel, and Harry Potter), but there are a few scenes that give you pause to wonder why they went with a certain animation. Hardly movie-breaking. Nonetheless, the settings, the varied color palettes, how each environment reflects its hero, the cinematography, and the rich score make this movie so vibrant, it should be difficult for anyone to criticize that aspect.
While I imagine many folks wanted more from a villain, that was never Steppenwolf's obligation, nor the purpose of the film. The film itself is about the League coming together. The League fighting. And the League lighting a path to a new era of hope; the Snyder loyal will argue this was the plan all along: construct a conflicted world that has no shortage of pain, despair, and mistrust... which will find the light with Superman's sacrifice, and the League's formation. And I would agree with them. Even with slight inconsistencies from Whedon to Snyder scenes, this film and its lore seem thoroughly fleshed-out.
Steppenwolf is a lackey. Darkseid will come one day, and the world will tremble. Until then, who knows? Starro? Amazo? Grodd? We'll see.
Stay until after the credits.
I give it, flaws and all, an 8.5/10. I found it similarly enjoyable to the Avengers. I would've likely given it a higher rating if there were more content.
