This was a nice little change of pace within the DC Animated slate. For one, the animation style is significantly different than the rest of the movie, taking the look from Darwyn Cooke's graphic novel this is based on. Another, being set in the 50s gives the movie a fresh look at everything. There's a sort of innocence to everything that has a creeping rot seeping in. Some bad shit is on the edges, everything on the cusp of change. But the heroes (aside from Batman of course) are all nice guys just trying to do the right thing. And unlike the last one I watched (Crisis On Two Earths), the voice casting is really on point here. The standouts for me of this great cast is Ferrer of the Martian Manhunter, my most underrated super hero. But the surprise is Sisto, giving the best Batman performance outside of Kevin Conroy. Now the plot is typical end of the world alien shit. It's a bit convoluted and big. But the movie works on the micro level, the little moments between characters and what they're going through. It's a much smaller scale movie for the most part compared to other Justice League movies, taking its time to get to the big finale. It's a gorgeous movie with a great style and a great tone, giving us a unique take on the world. Gotta give it to them for shaking it up a bit. It's still an adult take, with some really hardcore violence showing up. But for the most part, this is not like the newer crop of stuff. Great stuff.
