In the pre-youtube/streaming/filesharing era, people were a lot more forgiving of clip shows. Not that they were ever good, but now they get rated as the absolute worst, rather than being average-bad, which is contextually more realistic.

Now you can watch "Ten times Deanna uses her telepathy to deduce the obvious" on youtube, so a clip show is far more redundant than just being a spruced up rerun.
