You don't have to go to the theater to see 2000 Mules.
For $20 you can watch it on any web browser at home.
They're going to open the dashboard 3 days before the event so you can test your devices and make sure you can watch.

If time is free, advertising, distribution and production was all free - I would be inclined to agree with you.
But, as Production, Editing and licensing costs to use music will all likely run into the Millions; I think you are asking for an awful lot.
I have watched most of D'nish's movies, and have found them all to be highly informative, well researched and exceptionally produced. I have no problem giving that man $20, and if there is a tip jar; will probably generously donate more.
