That's funny! Back in 2019, I purchased a 55" 4K TCL for my parents. Every time I see it, I'm very impressed with how it looks. They don't have any 4K sources, but it's still a very nice looking TV. The only complaint is that the screen doesn't handle glare very well, it's actually terrible, but I've heard TCL has improved their screens since then. I just purchased a 40" 1080p TCL as a Christmas present for my parents for their bedroom. The 55" TCL was Roku equipped. The 40" had the option of Google or Fire TV for the same model, I went with Fire. After you posted this thread, I looked up some 4K TCLs and they're so cheap! Now I'm considering a 4K upgrade.
Yeah, T2 and JP are still two "benchmark" movies for me. Not only do I consider them amazing movies, that I can watch a million times and still love, but they're always great for testing out new home theater equipment. Funny story, T2 was the first and second Blu Ray that I ever purchased. When I got my first HDTV, a 720p screen, I picked up T2 to test it out. But at that time, BDs were still pricey and knowing that I didn't have a full HD screen I decided not to purchase any more BDs. But after I got a 1080p screen, they had released the Skynet Edition so I ended up picking it up.

I mean, how can I pass that up?
BD prices have been reasonable for years now, so I've mostly been purchasing BD over DVD. Unless it's something that I really don't care and/or the price isn't justified. But UHD BD, the prices are still kind of all over the place. One trend I've noticed though, for the most part, is that the really popular movies are over $20 and the common movies are under $15. I mean, you're gonna purchase your favorites no matter what the price is. So I don't care if T2 or JP are over $20. But I was just looking up UHD BD on Amazon and some of the prices seem nuts. Like Fargo for $30 and Groundhogs Day for $25. I mean, Groundhogs day isn't a movie I'm gonna go out of my way to get on 4K. Heck, I didn't even bother to get it on BD. And I don't care what work goes into a remaster, or which rights need to be licensed, I'm not paying $30 for a movie.
But there are lots of great priced movies. Some that I've come across: The Mummy (1999) for $10.49, E.T. for $11.25, Casino for $10.13, and The Fast and the Furious for $9.99. Those are prices that I could impulse buy at. For $15-20, I have to think about it and/or really like the movie. Over $20, it has to be one of my all time favorites. I've always thought E.T. was a visually stunning movie. And the first Fast and Furious movie is a classic at this point. I'm not a huge fan, but I would definitely get it at that price.
But yeah, I doubt many people outside of real home theater enthusiast are collecting UHD BD. Laser Disc might be a good comparison. Now might be a good time to start getting UHD BD before it's too late. Best Buy announced that they will stop carrying DVD and BD in early 2024. Not that a big retailer can't make a misstep, but this might be the writing on the wall.
I've thought about getting an Xbox One, but I don't think I'd like to use it as a BD player. I like to keep as much wear and tear off of game consoles as possible. I feel like I could wear out an optical drive prematurely if I used it for movies. Entry level stand alone UHD BD players aren't too much. That said, it kind of sucks that things aren't built to last these days. Go back to the 80s or 90s, and you could buy a JVC or Sony VCR and as long as it wasn't abused it most likely still works today. But even when you stick to trusted brand names, I feel like DVD and BD players can just die without warning. It makes me worried about an investment in the media if I might have issues with playback in the decades to come. That is, unless playback becomes a cinch on PC with unofficial software.
Dammit, now I'm seriously considering getting a 4K TV! I'll wait until I set up that TCL for my parents. Even though it isn't 4K, I'd like to see how the newer TCL screens deal with glare. If they've improved, I might be getting a 4K TCL for myself!
