This is a descent movie, I really liked it. It does have a lot of language though. You will have to mute whenever Joe Pesci and/or Chris Rock start to talk (they say most of the bad words). The ending is very gory. But it is a good and entertaining movie!
Lethal Weapon 4 is a great film that makes up for the disappointing Lethal Weapon 3. Violence is very strong in this movie, so is language (i.e. f--k, s--t, and racial as well as religious slurs). Sex is not an issue with this film.
