What's your personal preference regarding stories that contain characters whose "alignments"[/nerd] are explicit as opposed to stories where everyone has their own justifications and flaws? I personally find the 1900's ideas of "BWAHAHA WORLD DOMINATION AND BABY PENGUIN GENOCIDE" "STOP RIGHT THERE, YOU VILLAINOUS SCUM!" a little... well, 1900s. "Villains" will always have some sort of justification (Sauron was bullied by hobbits as a young child... just kidding), but I rarely find that it's spun in a way that you honestly don't know which way the script will swing because there's no explicit "good guy" Examples of the first include almost everything MARVEL and DC, the Lord of the Rings trilogy, Harry Potter, you get the idea. Examples of the latter include Smokin' Aces (there are no good guys) and full-cast-crossovers (which are AWESOME): episodes/whathaveyou where characters from an entire universe are thrown together in a bizarre set of circumstances like Crazy Clover Club's rendition of the Nasuverse (If you don't know, don't look it up. TYPE MOON fans only).
