I haven't had lulls in anime viewing and I rarely rewatch anime these days (even my favorites). So I'd say that the anime that gave me "fresh newbie" feelings have been the anime I enjoyed the most over the last year:
1. Code Geass 1st season --- lots of crazy plot twists and likeable characters to follow. I got a lot of laughs from those plot twists. They were SO nuts.
2. Kanon (2006) --- Stories that took me away to a fantasy world.
3. Death Note --- didn't like the last third as much, but I enjoyed this because it was suspenseful, unconventional and fun. The evil facial expressions were classic.
4. Black Lagoon Second Barrage --- Over-the-top action and lots of crazy characters. Made me bust out laughing on many occasions.
5. Higurashi Kai --- Many layered plot, but I never try to figure it out. I just watch them as it come up. It's something to relax my brain to.
6. Darker than Black --- The ending didn't leave a permanent impression on me, but I enjoyed the series quite a bit considering it was mainly an episodic series. Beautiful artwork.
7. Toward the Terra --- Really enjoyed this space epic. Plenty of ups and downs and emotional turmoil.
8. Asatte no Houkou --- I like how the story flowed along very naturally and unforced. Too bad the manga went in that weird "hen" direction.
9. School Days --- A little TOO psycho for me, but I still found it to be campy, over-the-top amusing.
10. Heroic Age --- Thought the first half was weak, but I quite enjoyed the last few episodes. It was great having a more "out there" science-fiction anime because I hadn't seen one for so long.
