Perfect example of how nothing is thought through. While the battle with hundreds of shuttles and blinking lights is going on outside, there's a huge dramatic scene where Admiral Cornwell sacrifices herself after a torpedo gets lodged in the hull of the Enterprise. Pike watches the sacrifice behind a blast door.
But that raises a question ... If a *door* can stop the force of an exploding photon torpedo, why isn't the hull made out of the same stuff as the door? (Also, why aren't the transporters working either?)
