I really hated that kind of shit. ESPECIALLY back then(which I was an actual teenager, senior in high school, no less). I guess I grew contempt for all that "Yo yo yo, look how hip and phat weez can BE!" because it was all in my face. It's the reason I never got into Jet Set Radio, and the reason I hate the phat urban look of The World Ends With You(and probably why I'll never bring myself to play it despite hearing good things about it). When stuff changes to appeal to a specific demographic(by way of trend), it just feels phony to me. It's the equivalent of The Simpson's Poochie.
I'm on the opposite end of this opinion.
Dreamcast-era Sega made some brave visual design decisions, and pulling Sonic out of the "cartoon" mire that console mascots were stuck in at the time was one of them.
It wasn't an attempt to appeal to a certain "demographic", it was an attempt to differentiate themselves and breathe new life into game design.
