The Matrix Reloaded explores the difference between destiny and choice and whether choice is "an illusion created by those with power."
The Matrix Reloaded has many huge fight scenes-- especially ones with clones (Neo must fight 100 Smiths) -- zillions of explosions, and a 14-minute car chase and crash scene on a freeway, with bad guys who can turn themselves into ghost-like wraiths. The characters are constantly in extreme peril, some die, and one wounded character dies but is brought back to life.
Some passionate kissing, one sexual encounter (not graphic) with partial nudity (her bare breasts, his butt).
Relatively infrequent use of words including "f--k," "s--t," "prick," "damn," "ass," "hell," "Jesus" and "Christ" used as exclamations.
