Meanwhile, at the Hall of Justice:
Justice League vs. The Fatal Five returns to what is known as the DC Animated Universe, or Timmverse as it is also known. The art style and voice actors are directly from the show, with new characters to interact. Throw in musical nods to Batman, Superman, and Justice League Unlimited animated series, and this is nostalgia at its absolute best.
Is that the intended audience? Is this a film about young heroes for a younger audience? Are both audiences served?
