He walked around a forest for 45 minutes while the villains slowly kill each other with next to no motivation. During that 45 minutes all he did was watch people from bushes, shove a guy down a hill, shoot at someone once, and eat drugged up berries. Even once he does actually start doing things over an hour into the movie, its just a quick montage of him killing off a bunch of disposable goons who seemingly lack any peripheral vision.
The finale gunfight between Bruce Willis and the big bad that was built up as a rutheless killer since the first second he was on screen, 2 minutes into the movie, the man who had killed off his teammate as soon as he was alone with him, just for the heck of it, the man who supposedly killed almost a dozen rhinoceroses with a machete while he was on vacation, was killed with one shot, and his finale line was "Woah"
10/10 would recommend if you love trash films
Also it took half an hour for the first gun to be shot. Thats a third of the movie. (including credits)
