@FinalBaton:
You've got yourself a proper smorgasbord with all these classic titles to wade through
While I haven't seen
Dangaioh or
Vampire Princess Miyu, I saw
Gunbuster sometime last summer/fall and it probably was the best thing I saw that year, at the very least. Just amazing the way it builds up and then pays it off. But I feel it probably only works really well the first time, as I can't really see myself re-watching it too often. Just not built that way.
I think we had a pretty good discussion about what makes it tick compared to it's sequel, Diebuster, a couple of pages back but I wasn't able to dig it out at the moment. All I know is it left a huge impact on me and that I truly enjoyed the experience, perhaps especially on an audiovisual level.
As for
Vampire Princes Miyu, your enthusiastic thoughts certainly do make me interested, even if the genre isn't my favorite. I do love the artwork for it however, so maybe that can be my "way in", so to speak.
Black Magic M-66 makes for yet another good case why I love the OVA-era so much. It's nothing super great, merely interesting. Interesting and exciting. Perfect little pop corn experience that don't outstay it's welcome.
With today's heavy focus on marketable TV-anime, these smaller, more of less self-contained short-stories feel so incredibly full of ideas and variety. Something like
M-66 most likely wouldn't lend itself too well as anything longer or bigger than what it is, and I can't see it getting made today. The visual quality of modern TV anime has certainly gone up in a truly tangible sense, but the content sometimes feels heavily stagnated.
This turned into a rant and I sadly don't have too much to say about the M-66 itself, it was a while since I last saw it, but I too remember it as a fun, sometimes silly, ride that had me on the edge of my seat for it's duration, but ultimately didn't leave me with any long-lasting thoughts or feelings.
Which is just the way I like it
