I remember me and others, on HN years ago, complaining about how Netflix was investing too much money into TV and original TV while skimping on its streaming movie catalog (this was around the time its STARZ deal was ending). Turns out their strategy was exactly right. I like watching movies, but nothing gets my return visits like serial TV, such as "Breaking Bad" and "Walking Dead". Investing so much money into "House of Cards" seemed bizarre 5 years ago but now that Netflix has so much exclusive content, it's hard as a longtime subscriber to just quit it. even as someone who now subscribes to Amazon Prime and HBO. I actually like Amazon Prime's library, which can be augmented with content I buy from Amazon separately, enough to quit Netflix. But my parents really like the Netflix shows (and I'll admit to binge watching HoC, as shallow as it is), which is something Prime or HBO will never have.

edit: besides the Netflix-conceived shows, e.g. HoC and "Narcos", there are the Netflix-bought shows, such as Arrested Development and Black Mirror, and what seems like countless comedy specials, such as Louis CK 2017. Back when I thought HoC was a poor investment, I was thinking that one really great show a year wouldn't be enough to keep me subscribing year after year. But Netflix seems to be introducing exclusive content several times a month.
