NagiAsu slowly grew on my during it's first cour after a weak first few episode, but yeah, the "return" episode has me pretty pumped too. My girlfriend has been a big fan for a while so I'm guessing she's going to feel vindicated.
Actually, a lot of the shows I'm really excited for right now are carryovers from fall, with NagiAsu and Tokyo Ravens being the ones I'm most interested in.
And yeah, I did see Refrain. Liked the early episodes, didn't care much for the main route story. So basically, I think the same thing as every other Key anime I've watched. Maybe I'd like their main routes better if there was more focus on sappy romance and less on supernaturally inflicted deaths and revivals.
You might want to wait a bit on the Madoka movies - all the new stuff is in the third one and I don't think there's a good quality version available online yet. I caught one of the two screenings held in Vancouver.
You not watching Monogatari SS reminds me of the rule of thumb that when a video game franchise has a stinker, it's often the game that follows it up which takes the sales hit. Many of the episodes aren't told from Araragi's perspective and I'd cite Nadeko Medusa and Hitagi End in particular as among the best arcs the series has ever had.
Your list contains some really high profile stuff that I didn't actually finish - Titan (watching with friend who then went overseas, found out when he got back that he had watched a bunch of episodes while travelling), SNAFU, Minami-Ke, and Railgun - though from what I hear I watched all the good parts of Railgun S2. Oh, and Love Live, though you didn't list that.
I probably shouldn't post a list of what I did complete because some people might make pointed comments about my level of taste.
I'll make some comments based on your post to Triple R:
Shinsekai Yori - no brainer.
Sakurasou no Pet na Kanojo - about as good as Toradora to me. Which means I liked it, but less than what some others did.
Dansai Bunri no Crime Edge - only saw the first episode and was put off by it lol.
Uchouten Kazoku - excellent series. Best PAW production since True Tears albeit very different to what they normally do.
Rozen Maiden: Zuruckspulen - got about halfway and plan to finish it. Probably the best of the Rozen Maiden adaptations as it has a much more sombre tone.
Watamote - great series. Best awkward "black comedy" since Welcome to the NHK.
Monogatari Second Season - I'm pretty much done with monogatari franchise atm. Dropped it after Nise and Kuro after it turned into a full out harem.
White Album 2 - True tears style romance done by a different production team and studio. Loves it to bits. However, lack of production values and "artistic" merit brings it slightly down compared to it and ef tale of memories, which I consider the two giants in seinen romance drama.
Wolf Children - favourite Hosoda movie. For some reason I love sentimental familial themes even though I'm not a parent or anything.
Madoka Magica: Rebellion - haven't seen any of the madoka movies actually. I should remedy this.
Hanasaku Iroha: Home Sweet Home - great movie. spent most of the time on the stuff which made me like the tv series, though I could do less of Yuina being obnoxious and annoying and Nako's kids causing unnecessary drama.
Director said she's powering up Tamako for the sequel and the PV had a more sombre tone. Enough data for me to make a prediction.
Shinsekai Yori and Wolf Children (saw it twice, the second time in a theatre since they screened it at the Vancouver Internaitonal Film Festival) are my front runners as well, I think, but I wouldn't give WA2 a clear cut third - see Triple_R's wall for what I loved this year.
