But the episode I defend to the end is "Shades of Gray". Given the sheer limitations imposed on it by time and budget, they produced an episode that had some pretty good moments, most notably from Riker just before he passed out, and the three leads at the end. And I liked Pulaski better than Crusher anyway. And YES, it was a clip show, but the clips were pretty exciting.
This is the one I defend. Watched it lats night in fact.
I think it really showed the great variety of episodes we'd had in just two years, with the show able to pivot from comedy to high drama very well - something that TNG would do well and I think DS9 would run with. And at the time without the ability to easily rewatch, it acted a good 'summary' of the first two years and at that point recapping episodes some of us had seen almost two years before.
It allowed Pulaski to be a doctor doing doctor stuff in her final episode.
It played the Troi/Riker tension well.
And it's almost 20 minutes before you even get the first flashback, there is stuff in there that isn't flashbacks - there is a story built around the concept.
