Lethal Weapon 4 is an incredible 4th installment and imporves over it's predecessor. Mel Gibson and Danny Glover are incredible once again with perfect chemistry. The humour is extremely funny and Chris Rock is definitely a welcome addition. Jet Li is a great villain. Richard Donner's direction is great as usual, resulting in some of the biggest and most enjoyable action sequences in the franchise yet. As with the previous installments, the music by Michael Kamen, Eric Clapton and David Sandborn is really good. It even has a surprisingly strong emotional ending. However, it does follow the formula of previous installments, giving it some predictable moments.
