No, but those of us who started watching the show from the beginning were turned off by season 3 onward. Also, at what point did they stop existing in the 50s and transport themselves to a netherworld where time didn't exist? Modern music, modern hairstyles, etc. Blansky's Beauties, Mork and...
I will buy the first 2 seasons definitely. Those were the only 2 seasons of Happy Days. Seasons 3-11 were The Fonzie Show, of which I have no interest in having.
