Deadpool/Fridge

Fridge Brilliance

 * Even as a casual Deadpool fan, I have to wonder exactly why he's so bloody popular at the moment. So I looked at the state of the Marvel Universe at the moment, and it became painfully clear. In a Crapsack World where you can barely tell the heroes from the villains and don't know who to cheer for, where Spider-Man made a a deal with the Devil and many important stories are indistinguishable from bad fanfic, Deadpool is different. He points out the absurdity, he's just as confused about good and evil as the rest of us are. And most importantly, he's actually funny, when damn near everyone else is painfully serious about wearing spandex and beating up other weirdos wearing spandex he's at least trying to crack funny jokes. Deadpool has been a shining ray of light in the darkness of the Marvel U, as goofy and fun as the Silver Age without the preachy morality, and reminds us who we're reading these damn things in the first place. - Sabre Justice
 * Stinkoman 87 just wants to add something: he's funny, but in a raunchy way, and uses guns. Deadpool is what would happen if someone made Spider-Man in the modern age.
 * He also strikes a good balance between "Ax Crazy murdering sociopath" and "Guy who honestly wants to do the right thing but keeps getting the Deadly Change-of-Heart". Just bloody enough to be badass, just annoying enough to be hilarious, and just messed up enough to be sympathetic.
