So, today I took my boy to see A Complete Unknown and I'll start with stating that was the tamest R rated movie I've ever seen, unless casual and frequent cigarette smoking now elicits such a rating. As you surmise, seems as if the studio may have pushed for it?, but no idea why a PG-13 rating would not have served similar purposes. Oh well. . .
I'm proud to say my boy stuck it out for the full 2 hour, 21 minutes, although it was a tough hang in between the musical performances. I thought we'd have the theatre to ourselves for an early matinee on a Tuesday, but there were a lot of seniors in the crowd (our whole row was full) due to the Tuesday discount rate, so unfortunately I wasn't able to answer all his questions (and there were a lot), but I hope it'll stick somewhere in the head as a pleasant memory as he gets older.
As for the movie, I enjoyed it a lot, even with the liberties taken with some of the historical accuracy. Chamalet and Norton were really good and hey, anytime Johnny Cash can be prominently worked into a storyline, I'm not going to complain. I've waned on listening to Dylan in recent years, not for any reason other than kids/listening to other music, but it certainly fired up the love for Dylan's music, particularly from that time period. Highway 61 Revisited was cranked on the drive home and a revisiting of the catalog is due.
