Grossie bombed. The reason is quite simple. The successful variety shows of the 70s starred people who were outstanding at improv. So many people (sticks up hand and waves) long for something like the Carol Burnett Show.
This is not rocket science. Lame "stars" won't attract an audience. Genuine yucks will. Want a hit variety show? Combine the cast of Drew Carey's old Whose Line Is It Anyway? show with the "stars" and musical acts.
