I tried watching a few 4K movies.
Dracula 2025 4K Atmos. I stopped after about 30 minutes. Just couldn't take it - I thought it was so stupid.

The Roses 4K. I stopped after about 45 minutes. Just couldn't take it either.
I did finish watching The Craft 4K, Rambo First Blood 4K, Rambo First Blood Part 2 4K. I heard their 4K versions look great. Well, I do think they look much better than their older versions. But the fact is, none of these older movies look as awesome as any of the newer movies on a 150"+ screen when every single grain is magnified on 5,000 Lumen.
