I somewhat recently upgraded my modern game / movie watching tv in the living room to a 4k, and so bought a 4k player to go with. I've been loving it so far! The HDR is really nice on movies like the new Mad Max.
I do "collect" physical movies because I really can't stand being subbed to like 5 streaming services just for a movie or show here and there, and the damn things keep losing the rights; streaming services are going to soon be just as bad as cable TV with all the optional paid channel bundles. If I wanna watch King of the Hill I'll put in the DVD, thanks.
I just got the new 4k version of They Live yesterday, looking forward to watching it.
