So unrealistic that you could expect the submarine to fly at some point, (minor spoiler) depth charges droped directly at the sub busted some lights and pipes then submerged at crush depth and survived. Thats just part of it, the amount of times they would realistically die is too much, besides of the classic and false self image of superheros that the US have in movies while ignoring historical facts.
