Nothing new about Johnny. And other SPOILERS.
The only thing that I hadn't heard or seen before is the pic of Johnny on an airplane pulling his face silly to make a funny face. The reenactments annoyed me. The actors voices trying to be Johnny....wish they didn't do that.
I wasn't looking for a Scorsese....would have HAPPILY dealt with boring transitions to hear mite of the tapes,
Ugh with the droning narratives of Saul's whining self focused driveling narrative.
Wrap up:
Small town clever Business man ends up being Johnny's manager. Johnny acts like a drunk addict and then finds The Lord. Meanwhile the manager is mean to his kids...quits his gig....which he regrets the rest of his ugly life.
