The great artistic sin of our age is never letting anything be done, never letting anything age, never letting anything stand on it's own long enough to become beloved. No theme or concept or character is ever allowed to rest until it's been done to death, they won't stop making more of the thing until it's been done so bad that everyone hates it, and even that will only buy you maybe half a decade, tops. Zombie culture.
Hell I think I might even be at capacity for Star Trek, and that's saying something coming from me. Until they will let it be cheap and chintzy and camp, until they'll put men in skirts and beige onesies again, until it can be about spacemen being very good friends in the face of the unknown again, I just don't think I need it.
