Sylvester Stallone’s 2 Biggest Movie Franchises Share Exactly The Same Flaw (& It Ruined Both)

The two biggest movie franchises of Sylvester Stallone’s career, Rocky and Rambo, were both ruined by the exact same problem. Stallone kickstarted his own movie star career with his Oscar-nominated script for Rocky, the story of underdog boxer Rocky Balboa rising up to take on the champ. After Rocky launched a blockbuster franchise, Stallone was dissatisfied with starring in just one and created a whole new franchise surrounding his First Blood character, grizzled Vietnam War veteran John Rambo. Both franchises have lasted for decades, and they were both ruined by the same problem.
