Could an MST3K style show that riffed on scripted television shows actually work?
If I'm not mistaken, Comedy Central towards the end of their time with MST3K actually proposed that idea to Best Brains Productions, who came to conclusion that it would've been difficult to riff on shows that are "intentionally" supposed to be funny like sitcoms.
I can realistically see somebody riff on poorly written and acted, unintentionally trashy dramas like say, The Secret Life of the American Teenager. I suppose that "hate watching" is more or less, a TV variant of riffing on something MST3K style.
