What people are grasping for here is that these are CGI models moving in 3-D, but they were based on Genndy Tartakovsky's stylized TWO dimensional designs.
For two-dimensional design, all those angles and swoopy bits add drama and impact. They're shape and composition aids.
In 3-D, the characters just look like retarded monkeybots. It's perfectly possible to do stylized 3-D well (The Incredibles) but you have to focus on the nature of the medium. You need round characters that still look like themselves when rotated and minimal textures that enhance the idea of materials rather than looking like a coat of matte spraypaint on a tuna can.
This kind of bad design is distracting in a way that CG held back by technical limitations is not. When we were all playing games like the Ocarina of time or FF7, it was easy to accept people with claw-hands and triangle shoulders because everything looked that way. It was the nature of the medium.
Here Lucasfilms could clearly have designed any character models they liked, but because their deisgn team has been trained to be "spam in front of a can", they just blindly copied Genndy's designs and moved on to coordinating space battles, as usual.
