The show: "Beavis and Butthead" should be revived because it has a large following, that is - a big fan base, and is a classic comedy. To those who would say it shouldn't, why not? What harm would it do? Comedy shows make people laugh, that's not a bad thing. If you dislike the show, then you are simply stating your dislike, and not providing any reasons for it.
Beavis and Butthead should not be revived today; their time was the 90s and their time has passed. While Beavis and Butthead was the right cartoon for the time, their time has long passed, and they may not appeal to a new generation which won't be solely into crude humor.
The 90s was a period in which Beavis and Butthead could rise to prominence and become a huge cultural phenomenon. Today, however, our animation comedies are far more advanced in terms of comedic timing, style, and delivery. (Although, the legalization of marijuana in Colorado and Washington may significantly reverse those trends).
"Beavis and Butthead" belongs in the past. There are so many off-the-wall cartoons and animated shows now, it would be pointless to bring back the most famous two-dimensional deadbeats in MTV history. "Beavis and Butthead" was a show for morons and underachievers. As such, it belongs in the archives of MTV where it should stay in perpetuity.
I do not believe Beavis and Butthead should be revived. For those wanting to watch it, it is available on different formats and across the Internet. I do not believe the show was that good, it was just unique and had a knack for speaking to adolescent boys. There's no reason to create more.
