Most common reaction tend to be "how clearly everything sounds". And that’s a good one I think.
What I prefer to show is the opening 20 minutes of the latest Bond "No Time to Die". It’s a film within a film and has all entertainment you could ask for. Great action, marvelous pictures, big sounds and finally the subtile Billie Eilish (again!) theme. Beginning and end. No need for more. If your public don’t beg for it...
