If you're looking for a weekend project and have a movie/TV collection I'd highly recommend it. The base software is free and it runs on linux (and Windows/OSX).
Edit: Or that might be wrong and the framerate can be changed separately.
That probably doesn't help with things that aren't on DVD/Blu-Ray, such as some of their original content. I don't think you can get Stranger Things in that format yet.

I believe the majority of people don't watch Netflix on their computer, but instead on set-top devices connected to their TV's That may also include hybrid solutions like Chromecast, where something may be installed on a local computer (likely a phone) as well, but those generally already have DRM platforms installed...
Films I can't get there, I just pirate. I'm not interested in installing DRM platforms on my computer to be able to watch very heavily compressed videos if they haven't been yanked offline yet.
