Ah yes. I really enjoy watching Dune (or Openheimer, or even less bombastic movies) on my 65" TV with two rather tiny speakers [1].

Streaming killed theaters because movie advertisement basically stopped (the lesser problem), and movies are immediately released on streaming platforms (the bigger problem). Why go to a theater when it will be released on Netflix/Hulu/Amazon within a week or two?

Movies used to get several weeks (sometimes months) of theatrical runs, and then there was at least a 90 day window (often longer) before home releases on VHS/DVD/BluRay. Now theaters are fighting for at least a 45-day window.

[1] Well, a 2015-ish Sonos soundbar and two IKEA Sonos speakers.
