Has anyone else seen this awesome buddy cop series? If so, what is your favorite movie in the series as well as your least favorite? How did you first discover the series? My favorite movie in the series is Lethal Weapon 4 (which is also my favorite movie of all time) and my least favorite in the series is Lethal Weapon 2. I first discovered the series when I was a kid because of Grandma having Lethal Weapon 4 on VHS which I quickly became fascinated by (mainly because of Jet Li). I then saw Lethal Weapon 3 which I think Grandma also had on VHS and then I saw the first two films after buying the entire series on DVD.
