I first heard of the Question when the Justice League cartoon became Justice League Unlimited. He was introduced in "Fearful Symetry", and although his name was not mentioned, and he had no powers to speak of, I knew he was incredibly cool. I began researching his character, and my hopes of finding any comics about him dwindled. He was such a minor player, how could he ever get a compilation like Batman or Superman?
I don't know what triggered it- maybe Question's role in 52, or the sudden resurgeange of interest in Watchmen -but Question got his compilations, and thank God I found them.
Question is not like most super heroes. He has a simple costume, and lacks over-the-top themed enemies. He lives in what could be deemed "the real world" and fights real criminals. Now, I normally prefer some fantasy elements in my comics, but the setting fits the Question incredibly well. He needs no Joker, nor Brainiac, nor Gorilla Grod. He needs corrupt politicians, street thugs, and gangsters. This, coupled with excellent writing and stylish art, allows the book to transcend being silly, and so it becomes film noir told in panels.
If you ask me, the Question needs his own movie. Who knows? Pending the success of The Spirit and Watchmen, it might happen. For now, though, we have the source material of the comics, and they are so amazing, you can't go wrong.
