It's literally the thing that keeps me coming back (to the seas). I have paid for the services, and the service they provide has been steadily degraded. I still have Prime because they haven't fucked up delivery to my home (yet), but I don't even open the app on Roku anymore, I just download whatever it is, because I have no interest in dealing with their shit interface and then having to watch ads after.
If a service can give me a simple, easy to use interface, good search feature, good quality, and decent enough content, you've got my money. That's just too much to ask these days, so I'll just donate to the site(s) that provide alternative services.
