Last week I got John Wick 2 and Prometheus when there was no discounts but the guy there he know I purchase from Amazon and knocked off $10 for the both of them so I bough them.
You will not be disappointed with prometheus. Even before the Movie starts (on the Main Menu) you will be startled by the PQ.
I watched this on again on bluray a couple weeks back and loved it this time around.
Maybe it's an upgrade if its in the 2 for $40 UHD sales that JB have jumped on to compete with Sanity. I never took nay notice of this title on Sunday. Just saw that JB didn't have UHD copies of Alien Covenant or John Wick 2
I would say that any TV that has the Best contrast and has the higher nits at say 10% will be the best to see this movie.
The Funny thing is the LG is well known for not being good in black and dark movies like Unforgiven, Deep Water Horizon, and others but in Prometheus its somehow shown to be different and the Movie is Dark. Maybe because the dark scenes have some good HDR bits in there to light it up when its dark.
