I consider these to be the definitive versions of the movies. I can’t think of any improvement that would be anything but a minor enhancement of these versions.

My parents side stepped having this conversation by letting their first child serve as a negative example for the rest of us

I have a deslopped setup that I’d recommend, but keep in mind all of my stuff is a few or more years old at this point so the newer models may not behave the same.

• an LG oled that has never been connected to the internet, though I did do a firmware update when I got it using the usb port. If I remember right, the factory loaded firmware was limited.
• an nvidia shield tv pro with updates disabled. These are android TVs so they can run the real netflix/prime/whatever app that you want, but they’re unlocked enough to let you put custom apps and disable system apps as you like. Updates needed to be disabled because the current version of the launcher added ads, but you can alternately use a custom launcher if you want to keep updates enabled. I keep mine separated on the network to limit any damage it might be able to do if there’s any security issues.
• a logitech harmony companion remote. They stopped making these a while back, but they continue to be supported. I may swap this for a Flirc Skip 1s if it stops functioning.
• a minipc running linux. I have a sort of nostalgic channel surfing interface video player thing I’ve been working on that runs on this, but you could also use something like this in place of the android tv entirely. A good mini-pc will be small and silent, a usb IR receiver will let it read commands from a remote control, and the GPUs in new ones are even capable of gaming directly, but can especially handle streaming well if you have a gaming PC elsewhere. If you want that, make sure you find one that can do 4k@120, a lot can only do 4k@60, and will only do 120hz at 1080p.

No ads, no bs buttons on my remote, it all works together with my audio setup and it’s the same experience every single time I turn it on.
