The Worst Sub Movie, Ever

I know, I know, there are many movies that could lay claim to this title. And I'm excluding documentaries; when I hear someone on the History Channel telling me that all the lights in the boat turn red at night so the crew has some sense of the passage of time, or when I see an electrostatic precipitator labeled as a "Washer/Dryer", I figure that's just the crew messing with the folks making the documentary. It's the fiction movies that bug me, because they're always way over the top, yet most people assume they're dead-on accurate.

So my candidate for worst sub movie, ever, has to be Sub Down. I could point out all sorts of weird little screwups (like having the crew fighting fires in steam suits, or radiation meters that read out in curies when the reactor is leaking what can only be antifreeze) but I don't have to. Here's a direct quote from the movie; judge for yourself:

The story so far: The USS Portsmouth is conducting scientific research under the north pole when they're accidentally rammed by a soviet sub. The boat ends up on the bottom, with all sorts of internal damage. Everyone in the forward half of the boat dies, except two civilian scientists. The CO, the XO, and the COB, along with about half the crew, are trapped back aft. One of the civilians, Rick, is talking to the XO via a sound powered phone:

XO: What are you doing for power, Rick?
Rick: I connected up two of those big 48-volt batteries directly into the Instrument and Control bus.
XO: The ones that are two feet by two feet, or the ones that are about four feet by four feet?
Rick: Four by four.
XO: That was very clever. The only problem is you're draining the power we need to start up the reactor. [to the CO] Captain, if we use the High Voltage Cutout, we might get enough power to the reactor to get it online. (emphasis mine)
CO: Let's make that happen.
Anonymous Nuc: There's no breaker on that line.
CO: It's all we've got.
XO: Alright Rick, here's what we need: There's a large switch box down by the batteries that bypasses the main circuits. You need to switch it in.
Rick: No problem.
XO: There's a potential problem: it carries 700 amps. If there's a short in the reactor circuit, the box could arc.
Rick: Great, I could blow up like a land mine.
XO: It's our best shot, Rick. We're getting a little "critical" on this end.

No, I'm not making that up. If you don't see why I thought that was amusing, talk to one of the guys back aft. And, in case you're wondering, the guy listed in the credits as the "Nuclear Submarine Advisor" wasn't Clancy, though with dialog like that they must have compared notes.
