PT Episode III Ending, the Venator?

Or maybe it was an intentional narrative decision. Or it was because it was cheaper to use a bunch of identical clone models rather than create a slew of individualized human bridge crew models for each and every scene on each different ship in the series. Either way, it doesn't contradict anything or violate any continuity. Most of the ships were crewed by clones, at least early on in the war. Some ships were crewed by normal humans, and maybe this became more prevalent as the war neared its end. The crew shown in Episode III was one of these ships, and it was shown to emphasize the transition from Republic to Empire. What's the big deal?

 

In the Republic comic series there are a several human military commanders. Could be that because space battle requires a lot of strategic and independent thinking rather than battle reflexes they got some of the Republics best military mindsd to be naval commanders, rather than clones.
