I'm currently watching The Melancholy of Haruhi Suzumiya, Maze, Ranma 1/2, and Maison Ikkoku.
I dropped Urasei Yatsura and Gintama for now. I'm in the mood for continuous stories right now, and they're just too randomly episodic. I'm sure I'll come back to them at a later time.
I had actually finished watching Maison Ikkoku, but now I'm re-watching at a more relaxed pace. The story was so good that I put in some marathon sessions to watch the last 1/3 of the series. Great, memorable ending set! Now that I'm re-watching, I'm enjoying how the characters are gradually developed, noting when significant events happen that affect later parts of the series. What a wonderful piece of work!
Maze is one of those animes that I have to be in the right mood for.
For the Melancholy of Haruhi Suzumiya, I need to be fully alert and awake. The dialog flows so fast sometimes that I miss quite a bit if my mind is drifting. Fun, interesting series, though.
Ranma 1/2 is just enjoyable so far. I'm just a few episodes in, so there's quite a bit of exposition happening.
