"A defining moment when you know that your favorite television program has reached its peak. That instant that you know from now on...it's all downhill. Some call it the climax. We call it jumping the shark. ... The aforementioned expression refers to the telltale sign of the demise of Happy Days, our favorite example, when Fonzie actually "jumped the shark." The rest is history." http://www.jumptheshark.com
Now, personally, I don't think B7 EVER "jumped the shark." Any dissenters?
As to the other fandoms, well.... I was sorting through old tapes, to decide which ones could be re-used, and ended up putting on the "maybe later" pile, episodes of Time Trax, Mann and Machine, the Visitor, Space Rangers, Seven Days, G vs E and on and on. There's usually only one episode, tucked in between other stuff I wouldn't mind erasing, so I end up keeping the tape till "maybe later." (I've also got a practically complete run of "Doctor, Doctor," a half-hour comedy series starring Matt Frewer.)
I GOTTA get rid of some of this stuff. Later. Maybe.
