This is an amazing movie, and visually one of the very few TRUE 4K movies (film, effect, post-production all 4K or nearly 4K) out there. First, if you are not ready to sit down and put your mind into the movie, don't bother watching it. It's complex, and deep. It's about family, selflessness, sacrifice, and the amazing vastness of time and space. I would consider myself a technical person, and a reasonably intelligent person, but only after my third viewing (today, finally got the UHD Blu Ray and watched the third time) do I fully understand everything that was happening. About 3/4 of the way through the movie goes into some pretty crazy territory, but it actually all makes sense once you fully understand what is happening. Things like black holes and worm holes and the effects of gravity and velocity on time and how that would effect the travelers vs. those they left behind are intense subjects. Leaving a dying earth and a seemingly doomed family including young kids behind to have some shot at saving their future is an intense concept to me as a father. There is no way to quickly tell a story this deep or technical, and I can see how it just might be too much for many.
As far s the picture and sound, wow. First one negative, the voice tracks lack gain and is too quiet. On a TV it might not matter, but on a home theater, you will need to crank up the center channel a bit. And the bass / low frequencies are truly something to behold, the cleanest and most powerful I've ever heard on a movie soundtrack...I brought the sub-woofer down about 1.5 db. Once properly balanced, the sound track on this movie will absolutely amaze those with a good home theater system....it will rock you, and to me it surpassed movie theater sound by a good margin. Picture is simply stunning. Shot partly on 35 mm and partly on imax 70 mm, and then combined with 4k and 5.6k visual effects and a 4k digital intermediate, this is as good as it gets today. Unlike most "4K" movies that are really fake 4K, this is the real deal...no shortcuts. On my 70" 4k Samsung TV, it looked truly amazing.
For those of you complaining about the streaming version not impressing you, please understand something. If you want to see REAL 4k quality, get a 4k blu ray player. 4k streams are so compressed and lossy compared to a UHD Blu Ray it's like night and day. Streaming may be the future, but it is not the present, at least not in 4k (and I'm an avid cord-cutter to boot). Neither providers or end users have the bandwidth to process a true UHD Blu Ray quality stream at this time, period, end of story. "4k" streams are a JOKE compared to UHD Blu Ray, and a bad joke at that. LG now has $100 UHD Blu Ray players, and it's worth every penny, so consider one if video quality is super important to you your family as it is mine.
For someone who has nearly 3 hours to devote to a pretty intense movie with some of the most amazing video and sound you have every encountered, it's well worth the time. For those wanting something light-hearted and quick-paced, look elsewhere.
