Lethal Weapon 2

A worthy sequel. In fact, I think it's a bit of an improvement, with tighter plotting and more kinetic action sequences. I also liked, to my surprise, the addition of Joe Pesci as a witness Riggs and Murtaugh are protecting. Yes, he's more than a tad annoying, but he's annoying in a mostly funny way. I also very much liked Mel Gibson's love interest, played by the cute Brit Patsy Kensit, who unfortunately never made it very big. The sequence with the bomb attached to Murtaugh's toilet is classic, and the shot with the woman cop getting blown off her diving board is (unintentionally) hilarious. Also side-splitting: the aging henchman played by Derrick O'Connor, who becomes a master of kung fu whenever the shot gets dark enough for a stunt double to take his place.
