I am probably the only person planning on seeing Slyvester Stallone and Rambo IV this weekend. Here are some statistics comparing the newest Rambo installment to the others: Number of people killed per minute in the Rambo series: Rambo: First Blood (1982): 0.01 Rambo First Blood Part II (1985): 0.72 Rambo III (1988): 1.30 Rambo IV (2008): 2.59
Add that up and it means one thing: Rambo IV has more gore than all other Rambos combined. Pretty amazing.
Also of note, I watched Rambo First Blood on Blu Ray (yes it exists) in preparation for Rambo IV. It remains a terrific film and, while it wasn't shot natively in Blu Ray (obviously), it looks damn good.
