I personally think Netflix price is quite fair. You get to see an entire show with several episodes. Or even two shows and more, depending how much time you have in month. Before streaming services you had to go all the way to a film town or somewhere to rent 1 thing, watch it in a day and then return it. Or buy a movie for about 20€.
If anything maybe Netflix could implement lower tier payments with limited amount of shows so if someone doesn't have enough time to watch much stuff they could pay maybe 50% only instead full price.
