I was born in 1976. *technically* old enough to have seen the last of the Showa films in US theaters, if my parents had taken me when I was 2 or 3...but they didn't.
Growing up I saw FCTW on TV often, and read about the others. I know Matango, Dagora, and Atragon played on TV where I lived (Creature Features etc)... but I probably just missed them. I did finally record Dagora from TV in 1991, and got bootleg VHS copes of Matango and Atragon in the early 90's long before MB DVD releases.
I also got Varan and Yog on VHS around 1991
...and rented The Mysterians from Blockbuster in 1991 as well
MB/TS release of Latitude Zero was the only Toho film that was entirely new to me when they released it on DVD
There are no more good TV Shows, only ones that haven't disappointed me yet.
