I'm sorry, but Angelic Layer was
animated by Bones
And if Bones did production (not simply animation production) then it is up to them or the people they hired to pace the show and all of that even if the original story is by Clamp. In case you didn't already know Clamp is a group of women who draw manga, not an animation studio!!!
Please let this be a good show. And let it be subbed... I thoroughly enjoy Fantastic Children but uh...
(btw dreamless, go check your rep...)
EDIT: regarding MUkou Hadan, it appears on MoonPhase as a movie with no link coming out in 2005.
