Okay, as far as I can tell Justice League: War, Justice League: Throne of Atlantis, Justice League vs the Teen Titans, Teen Titans: The Judas Contract and Justice League Dark are all part of the same universe. But is Son of Batman, Batman vs Robin, and Batman: Bad Blood also part of that storyline? And where does that leave Justice League vs The Fatal Five?
All of the films you just listed take place in the same DC Animated Movie Universe, except for Fatal Five. That one is a stand-alone movie, though it does take heavy cues from Justice League/Justice League Unlimited.
