Justice League: The Flashpoint Paradox (2013) is an alternate reality horror story (…), where The Flash (voiced by Justin Chambers) changes the past and transforms the present into world at war. In this alternate future, Flash has no powers, Bruce Wayne is dead (turning Wayne’s father into a brutal masked vigilante), and superheroes Wonder Woman and Aquaman are vicious warlords ready to destroy the earth in their blood feud. It’s the butterfly effect as comic book apocalypse and it’s a dark, brutal animated film. Warped-mirror versions of beloved DC heroes are turned into bloodthirsty warriors murdering one another (and even slaughtering children, albeit off-screen) until the frame is littered with corpses, and The Flash needs to recover his speed to set things right. This one earns its PG-13 rating (it features bloody violence and even some mild foul language) and is aimed at a more mature graphic novel audience. The voice cast includes Michael B. Jordan as Cyborg, Cary Elwes as Aquaman, and Vanessa Marshall as Wonder Woman. (Sean Axmaker)
