You pay to get rid of the commercials. There are no ads on my Hulu. There may be some mid-grade service but I don’t know what the point of that would be. You have to be a complete tool to watch ads in 2018.
I’ve had Netflix for about 12 years I think. I’m less happy with it every year. They blew all their cash starting a network war and now they have 100 shows of their own I don’t care about (78 of which are about standup or are standup) and almost nothing else. Their selection of classics, foreign language, silent, anime, etc, the majority of what I want, is terrible, and by “terrible” I mean I can only find four black and white movies at any time, that kind of thing. All the great DVDs they had from that boom era have all been scratched so even with a disc plan you are pretty much limited to newer releases.
Which is why I still buy most of the stuff I actually want to see on disc. As paid shill Nulity has pointed out you generally can’t buy a lot of steaming shows. You need Netflix to get that 4K fireplace video, that thing is really good. I also enjoyed Lady Dynamite a lot.
