Godzilla vs Kong (2021) 4K:
1. The surround mix is pretty constant and discrete.
2. Lots of low lows that'll rattle the walls.
3. The battles are reasonably entertaining.
4. Pretty much everything else (script, human characters, plot, performances) is idiotic. Nothing like the 2014 Godzilla or Kong: Skull Island, both of which I found fun. It'd be good to one day get a monster movie from the monster's perspective with no human characters to spoon feed the plot contrivances. If you miss this, you're not missing much.
Dragged Across Concrete (2018) BD:
1. Lots of discrete surround activity on this one (up your surround channels ~5dB to get the most out of it) including discrete 5.1 O'Jays performances (written by the director) during the credits.
2. I found it an enjoyable watch that's excellent in all respects.
3. Ridiculously cheap at the moment:

4. If you haven't seen any S. Craig Zahler flicks (Bone Tomahawk/Brawl in Cell Block 99), go buy 'em. They're good fun.
