Walk the line of a "meh" movie

Rating: 6/10 (8 February 2019)

I can not relate to this movie as it has lots of drug use and is about a famous artist. My favorite part of the movie was the end. As Johnny cash turns out to be really happy with his family.
The plot starts in the future. I beilive that the opening scene is the turning point of cashes life.
I did not know much of the history of Johnny cash or his era. But one can see that drugs and alcohol effect ones whole career and can damage all relationships. From what I can tell the history part of the movie was not a great factor to the plot.
I did not recognize the director or the actors.
This is a good movie if you like autobiographies, but either then that I did not really enjoy the movie as it was not the most entertaining thing to watch.
