Yeah, there's a new one, or there will be when it premieres next month. After re-watching the original, I have to ask, why bother?
I mean, on the one hand,
FLCL is amazing, and I can understand why you would want more of it. On the other hand,
FLCL is amazing, and nothing new could ever be as good as the original, so why sully it with pale imitations?
I enjoyed
Progressive and
Alternative for what they are, but what they are is big budget fan fiction. That's all that the new one will be either. I'll probably watch it; it might even be entertaining, but it won't be anything like the real thing, not even close.
The less said about 3D cell shaded animation the better.
