From Amazon Prime you can stream this 1 hour 43 minute family drama.

Dad Paul is played by Ron Silver. Mom Anne is played by Stockard Channing.  Jack is played by Anton Yelchin. Max is played by Giacomo Baessato.

Jack is 15 going on 16.  He is a typical kid who is on the varsity high school basketball team.  He and his best buddy Max gaze  shyly and longingly at their female school mates.  At fate would have it, it was only when Jack’s world seems to collapse that he able to befriend Maggie whose own father also turns out to be gay.  When Jack learns that Max’s father physically abuses Max’s mother,  he begins to appreciate his own family.

Despite the theme, this is a feel-good film in which Yelchin’s portrayal of Jack is pitch perfect and endearing.  This film is one of those rare gems that I somehow stumbled on.
