when I was younger I was a socialiser and hardly watched TV. Now I sit in a lot with my gf, which I like doing, and my lack of knowledge of TV in the 80's and 90's is obvious.
I wouldn't say a lot of TV is quality, some of it is absolutely a waste of space. Especially daytime TV. But even with freeview there are so many channels we have lots of things recorded, I don't know what people with sky on top of that must do with such choice. Apart from the football which is the only thing I miss since it was the only thing I watched since I had it 15-20 years ago.
There are good films, dramas, some amusing things and older comedies. I even sort of follow Corrie now but take the daft plots with a pinch of salt. The reality shows are crap, but it depends who is on them. The current line up of CBB is terrible what do they have people who have been on before ? The jungle with Ant and Dec is by far the best.
