Movies about movie making, or anything similar like putting on a theater show, or where a writer is the protagonist, are generally shit. It's narcissistic and usually cringe.

Once upon time in Hollywood is not great, but it has enough of Tarantino's strengths to make it okay for a single watch, but I doubt I'll ever watch it again.

Birdman made me so angry when it started and had a pretentious subtitle, I immediately knew the ads were misleading. I'm still mad I paid to see that in the theater, and take joy in Keaton thinking he won but having to sit back down. Whoever edited that trailer should be in prison.
