Freaks and Geeks. I watched every episode religiously. I even had theories about the characters which never came to fruition. Considering how it has become a cult series and many of its cast went on to have stellar careers, I’m surprised Paul Feig hasn’t convinced the cast to do a sequel, be it a film or a series for Netflix.
A close second being Models Inc. Guilty pleasure of mine in the 90s. It ended with an epic cliffhanger and I’m still mad I’ll never get to know what happened next.
