Most of the action scenes were basically excuses for the hero to effortlessly lay waste to a bunch of faceless robots. The animation would be over-the-top, rushing from exaggerated pose to exaggerated pose before striking the enemy for a big explosion. That's what I meant by that for the enemies.
As for the villains, look at Cytomander especially, and the faceless antispirals in the early-mid part of that arc.
There were some good action scenes, as I said, but most of it was just an excuse to look cool without much substance (bunch of clashes and then the hero pulls out the super move for the flashy finish.)
Kittan's sacrifice was used as a plot device to defeat an enemy, with the added drama of a character death. Kamina's death actually had a powerful impact on everything, the only thing that really happened with Kittan was with Yoko (and that didn't have much buildup to it beforehand.) Likewise for the twins who sacrificed themselves.
I didn't say anything about thematic depth, though I'm not sure the way they handled the first half helped that in terms of execution, it almost felt monster-of-the-weekish with the lieutenants.>>11054596
Everything in this kind of argument is your own opinion, there aren't any facts. I feel this way about it, so I provide an argument.
