Plenty of the usual spy-movie betrayals and killings, but the good guys are consistently willing to sacrifice themselves to save others. Also a theme of not only valuing many lives, but also individual ones.
Many intense action-movie stunts with unrealistic outcomes (for example, a character is thrown from a motorcycle at high speed without a helmet, rolls a few times, and is OK). The action is stepped up from previous chapters in the already famously stunt-heavy franchise, with more intense hand-to-hand combat and vehicle chases (cars, motorcycles, helicopters, etc.). Blood is rare. Shootings, knife fights, frequent peril. Deaths. A confusing bathroom situation could come across as a potential incident of violent gay-bashing that's thankfully nipped in the bud.
One unexpected kiss.
Infrequent strong language includes one use of "f--king," plus "s--t," "hell," "ass," "damn," "bitch," and "Jesus Christ" (as an exclamation). Middle-finger gestures.
