This thread has gone from shows that haven't been seen to shows nobody remembers. Either because they flopped the first time or were really, really bad.
I can't buy your either/or rationale for why some shows haven't been remembered. Television history is full of examples of shows that were cancelled prematurely despite being popular or critical successes. Exhibit A:
The Smothers Brothers Comedy Hour, which was by any measure a success, but was cancelled because CBS executives were in mortal fear of offending the sitting presidential administration. Conversely, there are many examples of shows that were kept on the air despite their lack of quality or great ratings, usually because they were relatively cheap to produce or were favorites of (the same).
