Justice League: The Flashpoint Paradox (Blu-ray release 2013-7-30) is the best DC animated movie I’ve watched.  Even though I’m not a comic book fan, I find that it has an exciting story involving superheroes becoming super bad guys that threaten the world in an alternate timeline.  Although I’m not convinced of the minor twist that reveals who changed the timeline, the many things that this movie did right outweigh this minor problem for me.  In addition to large-scale world-destroying battles, the father/mother-son relationships make this movie more emotionally satisfying than many others in the series.
