I want a space battle for this category and I'm torn between the single ship encounter at the end of Star Trek 2: The Wrath of Khan and the huge conflagration that occurs when the Reaver ships meet the Federation at the end of the Serenity. Both battles feature stunning examples of clever captaincy. Much as I like the shot of the Enterprise rising through the static discharges of the Mutara Nebula I'm going to go with the big shoot-out in Serenity.
Interestingly it relies on a similar gas cloud, nebula thingy as a plot device to set up a clever manoeuvre. It's short and nasty and shows off the brilliant special effects work. And stuck right in the middle is the Firefly class ship Serenity, crewed by people who are trying to do something smart and right.
