Honestly, it's way more concerning for movies than for gaming. Gaming and music both have viable digital alternatives that, while there are some pros and cons, gets you a product that's the same quality or better than what you could get physically.
Movies? No. Streaming still kind of sucks in terms of video and audio quality, and you can't buy and download anything. A proper ecosystem for this stuff never formed for movies. So when Best Buy and a few other heavy hitters kick physical movies to the curb? That becomes a huge domino. I don't like it.
