One of the best action movies of all-time in my book, and right there with Die Hard, Lethal Weapon still holds up so well thanks to the chemistry between Mel Gibson and Danny Glover. Even with the over-the-top staged fight scene at the end, this is just an all around entertaining flick.
(Reason I decided to watch it again today was saw it was on A&E and rather than watch a crappy edited version, why not watch the real deal in 1080p HD?)
