*sigh* Before I looked at this, I decided to go through this series from the beginning to keep everything in context.
You've put alot of work into this series. The art is acceptable and the voices are a good touch. But personally, I find the whole story confusing and boring and the characters uninteresting.
I'm assuming this is based off of something--I think you mentioned that in a comment on an earlier episode. However, I have to review this as a standalone story, and I must refer to previous episodes since this is one whole story.
For the most part, the characters seem to have no personality. It may be partially due to the monotone voice acting, but a big part of my apathy is due to the fact that there was very little development or explanation of the characters in earlier episodes. If they are popular characters, then fans may care, but I have no reason to care about what happens to any of them.
The whole series, for me, has been too over-dramatized--even now. Don't get me wrong. I'm not the type of person that just likes death and explosions. A good story can't exist without drama.
However, you focus too much on drama and not enough on the war that's supposed to be going on. You spend more time with dialogue than you need to. Like when they're deciding whether to explore the base or not. That scene was at least twice as long as necessary. In short, you need someone to edit your script.
The characters keep talking or stop to inflect when they should be focusing on what's going on in front of them. At one point in the series, one of the guys is in his frame in the middle of a fight and pauses to exchange a few quips with a girl, then he acts surprised when he gets hit by the enemy several seconds later.
Even if this is a dramatic series, you need to focus on the action more. The fighting just seems like a side-story to all the drama that's going on--and a poorly-explained side-story at that.
In this episode, I've seen more fighting than usual, but I'm still wondering what's going on and why should I care. I just don't feel a connection with any of the characters or what they're doing.
