'My Son' film experiment proves a mixed bag, but James McAvoy is brilliant

In ‘My Son’, Edmond Murray (James McAvoy) and Joan Richmond (Claire Foy) are distraught after discovering their seven year old son Ethan is missing. It is strongly suspected that the child has been kidnapped and as Inspector Roy (Gary Lewis) questions Edmond about his background, questions arise as to whether Ethan may have been targeted. Edmond starts to suspect Joan’s new partner, Frank (Tom Cullen), among others around him. With little evidence arising as to what happened to Ethan, Edmond begins to take the investigation into his own hands.
