Hi, Antonio Black from AMV Hell here!
Mostly...what now?
Not really heard of this anime you speak of.
My thoughts? Well, theming an AMV Hell around a specific anime is what the X episodes of Minis have been doing. But that's like, 5-7 minutes. Putting together enough material out of one anime to fill up most of a feature length AMV Hell is kind of a waste.
Here's a thought. Make this new anime and whatever ideas for clips come out of it into the "running gag" (like the overly long lead up to Kawaru's death from Evangelion in AMV Hell 2 or the Osaka clips in AMV Hell 3). This way its evenly spread out and has enough exposure to get a few more people interested in it.
This way, the plethora of ideas that will most likely flood into this new production-which I'd like to contribute to like last time

-will be able to vary.
There's way too many animes out there (both old and new) that have the potential to be something great in AMV form. Sustaining a full AMV Hell on just one anime is again...kind of a waste.
