Too bad, your missing out on a lot of great audio/video experiences.
A good multich rig can do everything a 2 ch system can, plus so much more.
We just don't watch big blockbuster special FX movies at home -- we go to the movie theater for that.
The living room TV gets used for "couples watching" -- couch time with costume drama stuff like Downtown Abbey, travel shows, or cooking shows, where super sound just doesn't matter.
All the other viewing of streaming TV series and such we watch on our individual tablets, solo.
I'm not a millenial, but I think our video habits are pretty similar to theirs.
