The Transformers, for example, were popular because they're sexy robots that turn into crap, and Thundercats are cool because Mumra's a total bad ass and the Sword of Omens is at the top of everyone's shopping list, but DBZ? It's just a bunch of weirdos flying around throwing fire balls at one another, and to me, that's a bunch of crap, so it's no surprise that just about all of the game starring these little punks have sucked the big taquito and Atari's Dragon Ball Z Super Sonic Warriors 2 for the Nintendo DS continues this trend.
Despite my superior intellect (achieved through consuming large quantities of mango salsa), I've never been able to figure out why Dragon Ball Z is so immensely popular.
