Yeah it's not a bad movie by any stretch for the genre, but one thing I really dislike about it (and most films of this vintage onwards tbf) is the CGI blood; it always looks so fake, and in my opinion, actually takes away from the violence, because it never really looks like people are actually getting shot up. I mean just compare to something like the original RoboCop, no comparison for visceral realism. I'm not sure if it was the 4K of Olympus I was uh.. "testing" before putting down any money for it, but some guy got shot dead and a perfectly formed shape of blood started expanding out from under the corpse, like the old Resident Evil games when you knew you'd actually killed a zombie, looked ridiculous. By all means use CGI to do elaborate set-pieces that can't be done for budget/logistical purposes, but bring back fake blood packs, it does *so* much for action films...
As for the 4K of Olympus, yeah, massive disappointment, although I pretty much expected this. It's legitimately one of the worst applications if not the worst I've seen, for DNR on 4K. I flicked back to the Blu-ray after and while things like skintones are much redder and "primitive", it actually looks like film in comparison. Horrible "fizzy" HDR grading; there's a scene inside the hospital before the attack and some patient is in a bed, and it looks like he's got a stadium floodlight shining down on his bed on the 4K compared to the Blu, it's so harsh looking, very unpleasant. The scene inside the cafe near the start looked truly awful, blatant edge enhancement and DNR, reminded me of some of those early Universal Blu-rays like 40 y/o Virgin. Yuck. A few of the close-up shots reveal some nice detail, but they're so infrequent, and they may well have looked similar on the Blu, couldn't be arsed comparing it all.
I would avoid buying UHD releases from Concorde. I am sure Lionsgate will release these on UHD next-just kidding Cas!
