Once Star Wars: The Rise of Skywalker is out, you’ll be able to binge all nine films in the Skywalker Saga in one place.
You would have to own physical copies or pay rental fees.
Even as an advocate of physical media, I find this appealing, especially since Disney+ will support 4K and HDR, so I won’t need to upgrade nearly two dozen movies to get great quality.
Many Marvel fans want to re-watch some of the previous MCU movies before The Infinity Saga comes to a close, but currently you can’t do that on streaming, even across multiple services.
