A more complete list of reasons I like the physical media:
* Bonus features (alternate endings, commentaries, deleted scenes, etc.)
* I always have it whether or not the distributor continues to exist or whether or not my internet provider is up
* I can play it anywhere
* I can format shift it to play on my phone, tablet, etc.
* If the movie was released in surround (be it the original Dolby Surround, or 5.1, or 7.1 or 7.2 or 9.1 or 9.2 or 11.1 or 11.2, my system can play it. Streaming, if you're lucky, gives you 5.1, if not, you need to revert to decoding analog surround after it's gone through the first D/A conversion)
* I always get to view it at full resolution, not dependent upon the slowest link between the streaming server and my viewing device
That's not to say I don't use streaming: I have active Netflix and Amazon Prime subscriptions, I have streaming televisions, a Roku 2 XS, a Chromecast, smartphones and laptops and PCs. I use Crackle and Hulu on occasion. Despite that, I still prefer DVD and Blu-Ray for the clarity that comes with the full high-bitrate content, the full surround sound encoding, and the extra features included on many movies and television shows.
