Did the psych team at the LAPD ever pursue the possibility that Riggs wasn’t crazy but was merely suffering psychotic episodes due to the weight on his brain from that huge, feathery hairdo? I mean, he’s one pair of latex pants away from being lead singer in a metal band. But I digress, which, thankfully, is something “Lethal Weapon” (1987) never does. Mel Gibson and Danny Glover’s tightly constructed, opposites-attract buddy-cop flick became a blockbuster and spawned sloppy sequels thanks to their chemistry (Danny’s buttoned-down, Mel’s unwound) and the fact that it’s fast-paced and not overambitious with the plot twists.
