aka The Rundown
A run-of-the-mill action movie with nauseating fight scenes and a buddy dynamic in need of a lethal injection. The Rock (when he was still called The Rock) is a 'retrieval expert' who goes to the Amazon jungle to manhandle someone who doesn't want to be retrieved.
I'm aware that he was basically doing what he did as Mathayus in The Scorpion King (2002), albeit in a more modern setting, but SK had heart and a sense of fun that wasn't forced. Welcome... has little of either of those things.
