As far as taking breaks is concerned, from intense anime that is, I sort of disagree with you because to me that reduces the tension I developed all along, and when I close it, it's all gone. And, to me, the problem is while episodic anime try to give unique episodes throughout, because of the lack of an over-arching story, I don't feel any weight or stakes or a sense of closure. I always feel like the creators are either holding back, or are being held by their throats, at least mostly.
And, I think I have to be more clear, Evangelion is an exception among the episodic ones I've watched. I don't know why I can't explain properly but something about episodic anime makes me want to avoid them.
