My media server is one of my favourite things in the whole world. Endless content in high bitrate video and audio. I have the editions I like (director's cut of Kingdom of Heaven is INCREDIBLE). No ads, ever. I watch it wherever and whenever I like. It works on all devices, online and offline. I'm never geofenced. Content will never be removed for any and no reason. Best of all, it's all in one place: movies, shows, and music. I can't pay for a service like that - and I probably would have, if I could.
I was paying for Netflix, but through a thousand cuts they pushed me away from streaming platforms entirely. I probably spend more on hard drives now than I would have with streaming subscriptions, but it's an infinitely better service.
My two favourite apps are Sonarr and Radarr. They make the collection process seamless.
