Is it a fighter? Nope! It's supposed to be huge, but it doesn't come across that way.

 

Most of the shots of the Command Ship during the climactic battle look fake. They're lit far too brightly. A complete lack of shadows doesn't help, either.

 

There's no sense of scale here. How big is the moon relative to the ship? How far away is it? Man... I sure hope they don't crash into it!

 

Uh oh... another preventable planetary collision! (I won't mention that the dark half of the moon suddenly changed sides.)
