The Flash finds himself amidst the World War III, and causing temporal ripple that creates a fractured reality that dispels anything ever heard about superheroes and the justice league.

For all its apocalyptic fate-of-the-world theatrics, this...[adaptation of] the 2011 graphic novel Flashpoint by Geoff Johns and Andy Kubert...has an emotional core to give purpose to its crazy amounts of mayhem. [Blu-ray]
The film feels unique and vibrant if only for the fact that it's the painfully rare DCAU title that doesn't revolve around Batman, Superman, or a Batman/Superman-led Justice League.
Years from now it may be looked at as the animated film that took the direct to video comic book movie market to another level of storytelling possibilities. Yes, it's that good.
