I'm gonna repeat what I said in another thread. Beavis and Butt-Head have no place in the modern world. Their appeal was that they were dumb slackers who spent all day watching music videos on TV. Their whole post-thrash, pre-grunge attitude was perfectly suited for the early-mid 1990s, and what they spent their days doing (watching MTV, loitering around convenient stores eating nachos and drinking slurpees, playing with garbage in junkyards and freeway overpasses) was relatable to kids of the time. I can't see teens today, in a world of Facebook and Youtube and reality TV, relating to these characters. Unless they dramatically change, and I really don't want that.
Which is why, if it does come back, I would want it to still take place in the 90s and be stuck in a sort of time-warp. Which would even make sense given the audience - this will mostly appeal to the late 20s/30-somethings who remember the show for nostalgia value. No teens of today will watch it. But I'm afraid MTV is just banking on the successful revivals of Family Guy and Futurama and assumes that B&B will be similarly successful. They'll probably force them to make fun of modern artists' music videos, even though just the idea of watching music videos on TV is a HUGE anachronism. Not to mention, how in god's name is this going to fit in between crap like Jersey Shore and Teen Mom? That audience won't have any idea what to do with this. If they really end up airing it on the main MTV, it'll flop and flop badly. They SHOULD air it late at night on MTV2, or maybe Spike or Comedy Central, and try to make it appeal to the people who it appealed to years ago, because there's no way it'll appeal to the same age group people today.
