Over the Top (1987)

An adventure directed by Menahem Golan, starring Sylvester Stallone.
A trucker who competes in arm wrestling competitions sees his son for the first time when he picks the child up from a military academy. They drive across the country to see the sick mother and have disagreements about custody with the grandfather. The trucker also competes in the world championship of arm wrestling.
Leave it to Stallone. In this film, he's the "Rocky" of arm wrestling. The final conflict is drawn out for extra suspense and to get the audience cheering at the screen. It has that late '80s style that I like so much and the pacing is perfect. Call me a softy, but I like '80s Stallone flicks. I'm rating it good.
