I didn't watch this and can't imagine how bad it must have been.
Early 90s humor really has not aged well. At the time, I loved Wayne's World, Beavis and Butthead. They're almost un-watchable now, because the humor feels so anachronistic to today's world. To a lesser extent, it's getting harder to force myself to laugh at movies like Tommy Boy and Ace Ventura. They really were funny at the time, but the jokes are entirely tied to a style of humor that felt edgy at the time, and then played itself out during the Tom Green era into the Will Farrell era. Now, the earlier stuff just feels corny.
Hopefully KOTH proves to have more staying power, but I'm not so sure. Its humor was very much tied to the zeitgeist of the late 90s and especially the early 00s. Some of this stuff is just hard to transport from era to era.
