First, I should identify the correct titles. Sylvester Stallone's Rambo franchise includes several movies: First Blood, Rambo: First Blood Part II, Rambo III, Rambo, and Rambo: Last Blood. So "Rambo +1" could be pointing towards First Blood Part II. The user might be confusing the titles, thinking they are sequential (Rambo 1, 2, etc.), but the actual titles are different.
