I have Netflix and Prime, and use iTunes for movie rentals, but I have no qualms about backfilling with Plex for TV shows and for movies not available via iTunes. Especially for shows that originally were available to me OTA or that were broadcast on a service that I had subscription to at the time they were broadcast. I'm just time shifting something I could have recorded at the time, right?
