It might be the formerly institutionalized, mentally challenged man with an institutionalized past. Or it might be the persecuted, homosexual male with little future. Louka caring for Kolya, learning to love him and receiving the healing that Kolya brings him as he heals Kolya. Afraid of his son's rejection, Tick pretends to be something he's not. His son matter of factly accepts his father, and Tick is able to return home physically and internally.
Characters explore deep themes including marriage and being fathers.
One great scene is where the dad promises that he will be at the son's big game, but gets tied up with work and instead sends an assistant to videotape it for him. When it is the sons turn to bat with the game on the line he looks for his dad but after seeing the guy videoing the game for his dad strikes out losing the game. The voice becomes more insistent, until he gives in and builds a baseball diamond, complete with lights for night games and bleachers for spectators. Look Who's Talking' contains a scene where John Travolta's babysitting character is confronted at the flat by the biological father. Powerful example of relationship over pure physical contribution.
