This is not a film with a twist, as some reviewers hope for on IMDB. It's a film about personal crossroads, growth and learning direction in life, even when you think you know it all already.
'Our Son' is all about their son and what his and their needs are as both parents have drifted apart.
This film is a slow burner, but it rewards you emotionally and maybe makes you see things as lesser 'It's a gay film' and more of how the couple could have done better for all three of them.
It's well shot, uses spaces and sets well, but does not get bogged down with showing every NY landmark it can.
Watch this one for a casual evening in, or for a Sunday afternoon movie.
