A few things:
I wouldn’t lump Beavis and Butthead in with Blossom.
I think the real downfall of the show is when it started to cater to whatever was big, pop culture-wise. For me, this was when Ralph got his own episode. Suddenly, “Me fail English? That’s unpossible!” wasn’t so funny anymore.
But other than that, I think this is pretty much right on the money.
What do you think?
