Eclectic Cinephile’s review published on Letterboxd :
80s-era action films at their best are some of the most well-paced, creative, and inventive movies. Lethal Weapon, with its fun mixture of comedy and action, is such a movie. Mel Gibson's Martin Riggs and Danny Glover's Roger Murtaugh, former cops turned veterans, stick together in one of the greatest buddy-cop action movies ever, set in Christmas (coincidentally, I am reminded of John McTiernan's Die Hard, which is also set around Christmas, stars a vulnerable cop as a hero, and has a black police officer as a counterpart/foil to the white hero).
Since this is a Shane Black-scripted film, the lines, the mix of comedy and tense action, the vulnerable heroes, the way all of these are connected somehow (things I find in Iron Man 3), — all of it just works
What Lethal Weapon does with economy and precision results in viewing pleasure for all of its 110 minutes, with details being brought up and made useful, action scene upon action scene is built up, and everything is done by people who know what they're doing and do it well.
