It wasn't so bad that I wanted to turn it off, but there was a whole LOT to make fun of throughout the movie. One thing that was funny was in the extras where they talked about wanting to make it as "real" as possible, trying to get all the painstaking details correct, but then they did things like, maneuvering the sub through a mine-filled canyon missing the walls and mines by mere inches, scraping the ocean floor TWICE, the ever-predictable water pipes bursting everywhere as they approach hull-crush depth. They tried to get some of the "Crimson Tide" vibe between the Caption and the Executive Officer by having the XO loudly contradict the Captain throughout their ENTIRE mission. I'm sorry but that is not getting the details about the navy correct. That XO would have been confined to quarters or placed under arrest for his constant mouthing off. That is only a couple brief examples of how unrealistic it was, to say nothing of the basic plot which is a mission to kidnap the Russian President during a coup, just to keep him safe. All that aside, I was entertained. Just don't go in thinking this is going to be one of the "great" submarine movies, because it's just not.
