The Question has undoubtedly been one of the great successes of Justice League Unlimited. He is certainly an odd character: a cynical, blank-faced, fedora, and trench coat-wearing paranoid Ayn Randian conspiracy nut. He exists on the far fringes of the League and can easily be described as something of an anti-hero. His obsessiveness and paranoia are clearly flaws, but these flaws give way to a deep desire to serve the common good.
He is certainly on of the most layered and compelling character in the series and that is nowhere more evident than in "Question Authority". The Question fits right in as the character that is trying to get to the bottom of the Cadmus conspiracy. When he gets to the bottom of it he discovers a secret that almost completely unhinges him. He comes to believe that Lex Luthor will instigate Armageddon after becoming president by killing the Flash and then being killed by an angry Superman. He decides to avert this disaster by killing Luthor before Superman can. This selfless, but perhaps lunatic, act fails when Luthor pummels the Question and reveals that there is more to Cadmus and the conspiracy than even the Question could unravel. The Question is captured and tortured only to be rescued by Huntress and Superman.
Superman is in an odd position in this episode. He is the authority that the Question doubts. Why does he doubt him? Well there is certainly the predestination aspect. But there may be a bit more going on here. Perhaps the Question does not doubt Superman's ability to do the right thing. Perhaps he doubts Superman's being the person to do the right thing. After all, the Question thinks that the right thing to do is to kill Lex Luthor. Its just that a "well known crack-pot" has to do it. Who knows?
Most of the action revolves around the Question, Huntress, Superman, and Cadmus. A minor subplot revolves around another Charlton Comics character Captain Atom. Captain Atom is forced to choose between the Air Force and the Justice League. The subplot works and makes for a great conclusion to the episode. It also demonstrates how the writers are really using characters intelligently. The minds behind Project Cadmus are brilliant even if they are insidious.
This is no stand alone episode. It makes numerous references to other episodes of the show. From the relationship between the Question and Huntress started in "Double Date" to the dark secret of Superman featured in "A Better World". There is a also a nice scene between Superman and Professor Hamilton that references several events from earlier episodes and from the Superman animated series.
The animation is of course excellent and the voice work is wonderful. Among the voice cast, Jeffrey Combs and Clancy Brown steal the show. Its also nice to hear Dana Delany as Lois once again.
