The Champ (1979)

A child is torn between his divorced parents--a loving mother and an alcoholic ex-boxing father.

I remember: despite having an interesting cast this movie is quite a sentimental and unexciting  custody drama.

Halliwell*: "A lush version, so little updated in mood that its tearfulness seems to have strayed from another age."

Maltin*1/2: "Voight is too intelligent to convince as a dumb pug, and Dunaway, as a loving mother, looks as if she wants to bed down with her kid in hopeless remake of the 1931 sudser. Young Schroder cires (and cries) convincingly."
