The Movie Talk reviewer didn't seem to me very high on 4K bluray.
Are 4K Bluray discs downward compatible with regular bluray? So far I have bought some films in VHS, LaserDisc, DVD, and Bluray. And there are a few where I bought the regular Bluray and then the director's cut bluray and then the special edition bluray.

No. When you buy a 4K movie, the BR disc is included.
Bud just said it; with every 4K UHD package (black plastic case), the regular 1080p Blu-ray disc is included.
To play the 4K disc you absolutely need another player, a 4K BR disc player. It just won't play in your regular Blu-ray player. The cheapest 4K BR players...hundred bucks.
And of course for best picture a 4K TV to go with it. But, it would play on a regular 1080p TV...down converted, or a 1080p front projector.
When you buy a regular 1080p Blu-ray movie @ release date the price is roughly between $20 and $25, less after couple months, or when they go on sale...Amazon or wherever they sell them.
To get the additional 4K version, it's between $25 and $30, @ the first release date. When they go on sale the 4K packages can be between $10 and $20.
I started this thread because for many people 4K discs are really no big deal.
For hardcore movie watchers who want the best 4K is another notch up, in high dynamic range, more accurate color palette, some extra detail in general.
There are more variables but in general that's the overall picture.
As for the sound the Blu-ray movie studios, to encourage people of buying 4K discs, they decided to make Dolby Atmos, which add elevated sound when you buy two or four more speakers and you install them in/on your ceiling, exclusive to 4K only (in vast general). But then you need a decoder too, by means of buying a new AV receiver or surround sound processor, to take advantage of Dolby Atmos, but you don't have to. Plus of course extra speaker cables to go above, and a new ultra high speed 4K HDMI cable. But the cables are very cheap, read very affordable...only few dollars.
Mike here is one of the top perfectionists on everything ultra high end audio, best quality music recordings, and top visuals with Sony OLED and his soon 4K front projection setup.
Mike is not alone on the ultra audio hi-fi side; Steve, Tang, Ian, Francisco, David, Bud, Davey, Bonzo, and @ least another couple hundred hi end gentlemen regular members. But I bet there are millions more who are out there reading and not posting. Videophiles, movie lovers we have that too, owners of the best TVs, opppo 4K players, Sony, JVC 4K front projectors, 7.2.4 setups, ...perhaps less than musicphiles.
We all love movies; me I love the movie soundtracks...like from 'Interstellar' that I revisited again very recently. It just blew me all over again, and it helps that I really like that film. Let just say that the overall experience is one of the most intense ones in the history of cinema. It's like listening to one of your favorite operas with the full cast and orchestral manoeuvres in the dark. Just name it, your favorite classical music composer.
4k is like what LPs are to the audio world. If I am allowed to a daring analogy.
Or it could be just the opposite; hi-def movie streaming. You are free to pick anyone you prefer.
The best in anything in life, to me, is to be free and happy with the one(s) we love.
