It suffers from an extreme lack of set up and context. All this stuff is thrown at you with barely any kind of explanation. And it doesn't even give you a moment to catch your breath before it jumps to the next thing. Heck, once Bellri got cut off mid-sentence because the camera couldn't bother with him before it had to jump to the next scene. Conversations jump all over the place just as they did in Zeta Gundam. It does indeed feel like an older show, which isn't inherently bad, but it also carries over the problems of that era.
I find a lot of the goings-on to be rather nonsensical and I often wonder aloud "Why?" Why is he doing that? Why is this happening? Bellri gets called to meet with some high ranking officials and Noredo is allowed to tag along because... Reasons? Isn't that a security risk? Why can no one figure out how to close the G-Self's cockpit hatch?
In episode 3,
Spoiler
why did they let Aida pilot the G-Self? Why did they let her anywhere near it? Maybe that researcher guy wanted her to escape, but what about Bellri? He made no indication of being okay with leaving his mother and defecting. Noredo also went along with it for some reason, though she at least attempted to get Aida to stop. They didn't even stop to consider the possibility that she'd run away.
At least the show is bright and colourful and not full of DESPAIR. I don't feel drained after watching it, though I don't have a huge grin on my face for the duration either. None of the characters have particularly grabbed me at the moment except for Manny. That could be because I feel her design stands out because it's the most normal looking.
