I've always preferred their DVD mailing service, though that took a huge hit in quality and the ability to justify using after they stopped shipping things on the weekend. Their service used to be much speedier and worthwhile, so now that it's slower to arrive and you get fewer discs per month, it feels like a waste. Especially when something is already currently rented out to someone else, who knows if it'll be available anytime soon. Despite all that, the DVD movie selection has always seemed far wider and more appealing to me.
The streaming side of things, I get it occasionally but don't really feel the need to keep it for any long periods of time. Maybe there will be something exclusive or more convenient than finding elsewhere and that can justify checking it out for a bit, but my tastes lean more toward older movies so the Netflix streaming service has never really been the ideal streaming service for me.
Despite that, I'm not really a fan of the fragmenting of the market with all of the rights holders pulling their content from services like Netflix and rushing to make their own platforms to make more profits for themselves. Way more convenient to just have one service than to have a bunch of stuff you want to watch being spread out through like 7 streaming services or something. It ultimately means less traditional media consumption for me because I can't be bothered to subscribe to all these disparate platforms, though I don't really care either because I'm more of a fan of physical media anyway.
It will be a shame if they wither away and disappear in the future, though as it is now they feel like a shadow of their former selves.
