Controversial Opinion: "Shades of Gray" wasn't THAT bad. Clip shows were a thing in the ‘80s. Some of us still didn’t have VCRs yet. I didn’t have one until 1990. So, clip shows were the only way for us to re-experience older episodes of anything, if they weren't strip-syndicated. Even though I wasn't watching TNG back then, I remember what it was like at the time, so I go easier on "Shades of Gray" than other people.
I asked my father for MONTHS to get us a VCR. Then he took me to Sears one day, showed me a VCR, and he said, "Do you know how expensive VCRs are?!" Then he pointed to one with a $300 price tag. $300 in 1990. That would be over $700 today. I couldn't understand it back then, but now I can understand my father's position. Today, I wouldn't want to just drop $700 willy-nilly. But anyway...
I get why they did clip-shows. Too many people just didn't want to spring for VCRs, and TNG wasn't being shown every day at the time. Clip-shows were like a "best of", except TNG didn't have enough "best of" material to justify it. That's as far as I'll go.
