The 80s was trying to sell you something else, so it needed to be quality enough to get you obsessed with the idea. The 90s was trying to sell itself, so the quality had to be within.
Both produced some top tier stuff for their time, though I think the 80s doesn't hold up well without nostalgia in a lot of cases, and without the principle behind it later stuff became a lot more generic and mass produced with the "linear storyline" often becoming the only common differentiator.
