There was also a TV series sequel back in the 80s that actually lasted a few seasons (1988-1991).

The 80s saw an explosion in sitcoms on American TV in general, as networks rushed to cash in on the success of shows like Cheers, The Cosby Show and what not.
On the other hand you had this new market for made-for-syndication sitcoms. And nearly all of these new sitcoms were shot on videotape, cheap to produce, and "family-friendly." And so you got a flood of poorly-produced sitcoms with rickety sets, has-been casts, cheesy writing and "wacky" premises, and attempts at revamps, reboots and "the New Generations" of various older sitcoms. The 80s was a Golden Age for bad sitcoms that looked like they were produced by cave trolls.
One of the first sitcoms produced directly for syndication was the notorious "Small Wonder".

None of the networks would pick it up (wonder why?) so the show was instead sold to a "consortium" of broadcasters. It did well enough that it encouraged other producers to sell
their terrible shows directly to syndication.
Some "notables" from this period include what was to be Suzanne Sommers big post-Three's Company comeback "She's The Sheriff" (actual tagline from an old print ad for this show: "She's The Sheriff and she's got the laughs...locked up!"

And perhaps even worse than "Small Wonder" was "Out of This World", which lasted a whole four seasons.

The premise, a girl hits her early teens and discovers that she now has strange powers activated when she touches her index fingers together. Her mother finally tells her the truth about her father, he was actually an alien who was forced to return to his home planet, and now she's developing alien powers. Her mother gives her a box that allows her to communicate with her father. Every week, she tries to solve some problem using her powers, only to make things worse. Her father gives her some kind of useless advice that
sounds like a lesson, as does her mother. In the end, she learns her lesson about caring and sharing and all that. Like with most of these cheap first-run syndicated sitcoms every joke is unspeakably lame and every punchline can be predicted about a minute before it arrives. It has a theme song that belongs to no real genre and a canned laughtrack that is used every time a character so much as moves.
Oh, and her father was voiced by one of the show's producers...Burt Reynolds.
