Sam Singer (Matthew Broderick) is a picklepuss who regards the world as his enemy, life as brutish, and the glass as half-empty. His face has sagged into a permanent frown.
To call him a misanthrope is an act of charity. Here is a guy who uses custodial visits with his preteen daughter as opportunities to accentuate the negative. He also happens to be a pot head whose weed habit deepens his funereal worldview.
Lucky for him (and us) in Joshua Goldin's Wonderful World, Sam has a roommate, Ibou (Michael K. Williams), a Senegalese immigrant whose positive life-force pierces Sam's gloom like a ray of sunshine. Where Sam hears the rumble of injustice, Ibou and his sister, Khadi (Sanaa Lathan), hear the music of life.
