An ORGANIC ship?
When the "bomb" gets the surge of electricity it needs to come alive, I just love the way that the inside of it is portrayed as veins and arteries with "blood" starting to flow through them, and how when it's fully powered and glowing when Colonel Breen comes to sit down and cook in its heat, you can see all the blood vessels cumulating in a spot near the front of it, like it was its brain. I always thought that was a very interesting concept for a Sci-Fi film of the time, one in which few TV shows have capitalised on, Star Trek and Babylon 5 among them.
