I'm with you...I never watch DBZ, but I hear my friends talk about it. And it sounds way too violent. And although I'm a HUGE Batman fan, I'm surprisefd how much violence is in Justice League, The New Batman Adventures, Batman Beyond, and The advntures f Batman and Robin.
But, for Adult Swim, before the show, they actually post warnings saying kids under 18 should not watc. But I watch Home Movies anyway.
