I didn't have trouble _following_ the plot or the relationships. They were just too tangled to serialize on a Twitter thread.
My summaries are all terrible, because the show does a great job of subtly setting stuff up for later use and I didn't realize it while trying to describe it as I went.
Or just gave up. Serializing the relationship chart into tweets would be unreadably humongous.
(Up to you if this is submerged homosexuality or just bros who have each other's back.
Either interpretation works.)
Maximilian is in love with Valentine, who is engaged to Franz. Franz gives this advice: there are other ways to show you love someone than marrying them.
Who does Franz love?
Albert, of course. He sacrifices himself to save his friend, but even before that it's clear.
Maximilian's disgust at aristocratic arranged marriages forces Albert to really dig deep into how he feels about Eugenie. The eventual conclusion is that he loves her, but it takes him a while to get there.
The main themes are love and revenge.
The Count is driven to get revenge for his betrayal, but part of the betrayal was because Morcef loved Dantes' fiancée, Mercedes. The question from early on was if she ever stopped loving him, or just moved on because he was gone.
The visuals are outrageous; instead of filling the characters hair and clothes with flat colors, they are windows to detailed backgrounds of their own. It's trippy.
The CGI for the mecha fights is... unimpressive. Luckily there isn't that much of it.
That's the show.
So, what's my takeaway?
Let's begin with the biggest shock: I was not expecting the Count to be Venom.
I mean, he did bond with an alien entity that made him nearly indestructible, I think that's a fair analogy.
Five years later, peace is breaking out across the galaxy. Is it because Haydee has returned home and restored things there? Is it Albert's stint as an assistant diplomat? Is it the lack of corrupt aristocrats in Paris?
Maybe it's just time healing wounds.
Albert confronts Gankutsuou and it retreats, leaving the Count mortal, and he now dies from his wounds.
He asks them to remember who he was.
Everyone but Morcef escapes.
Albert arrives and the Count uses him as a bargaining chip. Morcef surrenders to save Albert's life, but the Count doesn't want to kill him. Death is too easy.
Gankutsuou decides this is close enough and takes over the Count's body.
