21. Extreme Ghostbusters
Extreme Ghostbusters is part of the hugely popular Ghostbusters franchise and a follow-up to the far superior The Real Ghostbusters.
It featured a completely new team of Ghostbusters – as well as familiar characters Slimer, Egon Spengler and Janine Melnitz – and while it wasn’t as bad as most shows on this list, it was too adult and dark to interest it target audience.
It lasted just one season – although that one season was a whopping forty episodes!
