i completely do not understand the hate on system of a down. it seems like people just assume they are bad without really listening, simply because they fall under the umbrella of "mainstream". but let's face it -- they're not THAT popular. toxicity had like, 2 hit singles that got played on rock stations (but not usually on pop stations)... and that's about it. they happen to be a highly creative band -- they experimented with their music, instead of just cloning what was already popular. soad is one of the few mainstream bands i can listen to and think "wow, that's pretty fuckin fresh". i don't think they really have much in common with all the other nu-metal clones out there, other than some superficial elements of their sound, like down-tuning and groove-oriented riffs.
you all think you're being intelligent by instantly hating the mainstream, but i think it's pretty naive to make a judgment based on how much radio and mtv play they get (which isn't really that much anyway).
