Why can't we have good shows like this one?

I enjoyed myself immensely, but there was an undercurrent of anger, too, as I watched the first four episodes of "FREAKS AND GEEKS" on DVD during my day off yesterday.
How is it possible, I thought, that countless crappy shows clog the TV schedule, while an outstanding show like "Freaks and Geeks" can't even last a full season?
The plot of the series, which ran during the 1999-2000 season, concerned groups of varied students in a high school circa 1980, and their interactions with each other. In this respect, the show seems reminiscent of one of my favorite films, "Dazed and Confused."
Both also featured excellent casts.
LINDA CARDELLINI and JOHN FRANCIS DALEY, the Weir children at the heart of the story, are excellent.
So too are supporting cast members who have since emerged as recognizable actors of the small and big screen: JAMES FRANCO, SETH ROGAN and JASON SEGEL, to name but three.
Yes, I admit to a sense of resentment against the injustice of television when I watch "Freaks and Geeks."
If more people had watched the show at the time -- yes, including me -- perhaps that resentment could have saved it from extinction.
