I love, love, love Lethal Weapon. Along with Die Hard that is to me the quintessential early 90s action classic. I actually love 4 through and through, and don't get why its so maligned. Hilarious comedy and amazing action. The one I don't care for is #1 as its too dark and slow and Riggs isn't his usual hilarious self. #3 was so-so. But 2 and 4 are classic!
I don't ordinarily say that an opinion is objectively wrong, but, well ... yeah. You're wrong.
