All this talk of off-air taping reminds me of my own experience. For whatever reason, my dad taped all of Season 1, 2 and a half episodes of Season 2, none of Season 3, 3 and a half episodes of Season 4 (out of sequence as well? Aside from my dad's sloppy taping, does anyoneknow why that would be?), all of Season 5, but none of Season 6 (although I am just old enough to remember seeing that as it aired).
This meant that, when I started watching repeats myself years later on UKG2, I'd built up all those missing episodes from Seasons 2-4 quite a bit, so Season 3 is always tinged with disappointment for me, even though it's entirety solid.
I'm not fond of Season 6 at all, despite liking it in 1993, and the ending feeling like a lot to take as a 5 year old. Then again, it won't be long before it's properly being discussed, so I'll hold my tongue.
