Bad script โฆ. They had to keep explaining what the plot was. Just a way for tom cruise to show how many different stunts he can do. Dive down to a sunken sub, get the bends from coming up to quickly๐ค. Dying beneath the ice, car chase in a very very unlikely labarinth of underground tunnels, typical hanging off of planes and crawling around on them in mid air, parachuting one chute on fire- falling to earthโฆ bombs blowing up โฆ obviously, last 100th of a second before the world ends and he manages to save the worldโฆ. His destiny! Give me a break.
