The Lesson: If there was one thing that Trek was sorely lacking, it was a memorable bad guy. We're not faulting Eric Bana here - he did what he could with the role and even saw some of his plot cut out in the scramble to keep the film at a manageable length.
But BSG hit on a superb concept - albeit one adapted from the original show - about mechanical slaves rebelling, one that provided lots of drama and all the emotion anyone could need.
Star Trek needs a villain equally as compelling.
The Example: Dean Stockwell as the calculating Brother Cavil, who developed into a truly machiavellian type.
