Spoilers for the entire series: this is a rant. Consider yourself warned.
When I watched this, I was watching it for yuri content and little else. It wasn't the most painful thing I'd ever seen, and sadly I must admit the masturbation scenes (Hazuki) were unfortunatley the best part if you're going to be a loser fan-girl about it, because any scene involving Hatsuki (Eve) was just too painful to watch. Some of the episodes were dreadfully boring - like, most of the ones without Hazuki. Episodes with Gargantua were dull - and he just pissed me off. The only decent eps with him were of when he was a kid, and even then only the last episode of him with a kid was at all interesting to me because at that point they'd finally FOUND Eve and I was able to cheer Hazuki on in trying to talk Eve/Hatsumi into staying with her.
Which of course, didn't happen, and the whole thing being in Hazuki's head and she being the only one in her reality to remember Hazuki was ridiculous. How depressing is that?!? What is the POINT of an ending like that? I *almost* don't mind tragic endings if they have a greater purpose, but this one didn't. Eve is all powerful, she could choose to be with whomever she wanted to. I mean, its' not like she'd be missed at the library -- she'd already been GONE for hundreds of years, albeit in different worlds for 16 years at a time, but still, she never went BACK to the library or her real job in between those lives. So what DIFFERENCE would it make if she took one more little break and spent a life with Hazumi?
And Lilith's hat was UGLY and large and pointless. I hated it near as much as I hated that bloated little bird.
I liked the outer space episode, that was pretty good. The thing with the parents was CREEPY. I didn't see that coming at all.
Anyway. As much as I just complained, I don't regret watching it at all. I don't think I'll watch it AGAIN, but as far as shoujo-ai/yuri history goes, it is a well known example (unfortunately, heh) and to have a better frame of reference for yuri in anime, I feel more knowlegeable the more I watch. Like with lesbian films - I've watched a lot of them, and a lot of bad ones, too (like "Therese and Isabelle", this 60's French pulp black and white film that was SO terribly dubbed in the version I saw... it was laughably bad - to the point of where I'd actually watch it again just to make fun of it some more). So, yeah.
