This movie is basically what "Hail, Caesar" should have been in a sense. Or at least this is what I felt the Coen brothers were trying (yet in my opinion failing) to accomplish. Now Damien Chazelle has given us a worthy loveletter to the Hollywood of old. Highly recommendable watch.
What a stupid movie. I'm pretty sure I myself became stupider just watching it. Everything except a certain testicle-related revelation was oh so foreseeable yet somehow it still manages to surprise with seemingly endless amounts of ludicrosity in its story. Stay far away. There are too many excellent movies for all kinds of tastes out there to waste our finite time in this world on a cliché-infested disaster of this magnitude.
