DNAngel is adorable and fun and *does* end which is nice. I don't actually get that different of a vibe from the manga (which has distinct het pairings but plays constantly with the pretty boy double-entendres--as does the anime). It is fluffy and episodic but sticks to its overall arc well and, as I said, wraps the story.

Gantz I've only seen the first very few episodes of. It's *gorgeous* and -- from what I know of Battle Royale -- is up there darkness-wise with that. And it has a similar nihilistic streak. I didn't watch more because I'm rarely in the mood for anything that dark, but what I did see was fantastic.
