I watched Rambo Last Blood the other night. The supposed "final loop in the circle" of the Rambo films.
Very slow paced start, Rambo running a ranch, the half adopted niece he's been raising as he deals with PTSD by building vietcong style tunnels all under his property but generally having found peace with himself.
Then the neice goes on a trip to Mexico to find her real father, gets snatched by some local mexican cartel to be used in the sex slave trade, thus leading to Rambo returning to wreak bloody vengeance...but he doesn't actually. But by that point half the film has already gone, and then Rambo doesn't actually show that much tactical sense and getting the crap kicked out of him as an aging white guy in areas he shouldn't be in Mexico. It all culminates in a final 30 minute section of a cartel group running across the border to the US to invade Rambo's ranch, and the vietcong-style tunnels showing how much he remembered and got to kill of the invaders.
It had some nice moments, and some very stupid ones. All in all, it felt very unsatisfying.
