By this point in the series, it seems that they just aren't trying as hard with these films, which is kind of a shame. The Lethal Weapon series is really a good group of action films, but part 4 doesn't really seem to take itself seriously. It clearly had the biggest budget and probably some of the most elaborate stunts and action scenes (as well as some of the most exciting, such as that thrilling freeway chase scene), but many of the other elements of the film have deteriorated badly.
I think that with the addition of Chris Rock, while he delivered a satisfactory performance as far as the role that he was playing, caused the film to detract into too much goofy comedy, which unnecessarily diverted attention away from the surprisingly interesting smuggling plot involving illegal Chinese immigrants and counterfeit money. Joe Pesci was just as funny as ever, which is probably the reason the Chris Rock actually took away from the film as a whole. Pesci is all the comic relief that a Lethal Weapon movie ever needed, and Rock is another substantial addition of comic relief that just isn't necessary.
Danny Glover and Mel Gibson work great together for the fourth time; I'm beginning to wonder if they couldn't go on with this great duo forever. And of course, Renee Russo is back, with her and Riggs picking up with their quirky relationship, right where they left off at the end of part 3. But the person who really steals the whole show is Jet Li. Man, I thought Jackie Chan was fun to watch! Even though it's not all exactly real, this guy pulls out some unbelievable martial arts moves that give Lethal Weapon 4 a much-needed boost of energy. I wonder how long it will be before Jet Li and Jackie Chan come out with a movie together. Probably never, because if they worked together, no one could touch them, and if they were enemies, neither of them would be able to end up as the loser or the bad guy. Oh well, we can still hope, right? Even though the 4th installment in the Lethal Weapon series is not nearly as good as any of the previous three, it still remains a quality action film, despite its many weaknesses.
