From my early childhood I admired Michael Douglas. There were so many movies I watched purely because of his performance.
"Solitary Man" is an excellent insight into the male ego slightly after the peak.
At some point in our lives, we all felt the need to adjust our age, lifestyle or interests to see "whether we still have it". The lead character tries to go back in time with a visit to his alma mater, mentoring a younger man and hanging out with young girls.
The consequences of his behavior are the essence of this movie.
