L'héritage scandinave de Norén se combine avec ses affinités électives américaines : Embrasser les ombres, qui peut être lue comme une pièce sur Eugene O'Neill, esquisse la situation d'un auteur qui a cessé d'écrire, qui doit supporter que sa femme se drogue et que son fils ne soit qu'un vaurien.
Norén is considered Sweden's most prominent contemporary playwright of today. He wrote his first play at age 19. His first publication was a collection of poems - Syrener, snö (Lilac, snow) in 1963. His plays are realistic and often revolve around family relations and the impoverished and routed at the bottom of society. Norén became well known in connection with the murders of two policemen in Malexander in 1999. The culprits had received furlough from their incarceration at Österåker jail to participate in Norén's play 7:3.
