I'll go in airing order and without sequels, first:
Danganronpa: based on the original source, do want; I have no particular opinion of the studio behind it since it's quite new, so we'll see how it goes. Anime of the season potential.
Inu to Hasami wa Tsukaiyou: Gonzo, and the trailer was bad to boot. Do not want.
Gifuu Doudou!! Kanetsugu to Keiji: eh, not really interested. Deen behind it is a minus, too, so I likely won't bother.
Servant x Service: Don't know, might give it a watch, but I'm not exactly interested.
Gen`ei o Kakeru Taiyou: It seems set to be kinda bad as far as characters and tropes involved seem to go, but the technical realization interests me, so I will probably check it out anyway.
Kin`iro Mosaic: trailer was pretty bad and I'm not really interested. I'll likely skip this.
Blood Lad: Not my thing, and Brain's Base adaptations tend to just make me rage with their "endings" anyway. Most likely skipping this.
Makai Ouji: Devils and Realist: perhaps I might give it a go, although the premise isn't too convincing (and it's fujoshibat too, but this one might keep it to acceptable levels).
Choujigen Game Neptune The Animation: lol. Technically no, practically might watch it just to see how bad it can get.
Kimi no Iru Machi: Gonzo working on adaptation, do not want. It's sad, really, but I have low hopes whenever Gonzo puts their hands on something. I might start checking it out if feedback from people I'd trust on it is good.
Brothers Conflict: short title is BroCon... get it? And the character design speaks for itself. Checking the description makes me think of a fujoshi version of SisPri, too. Reversing the harem just changes the targeted demographic, but the substance is the same, so I'm not really interested.
Fantasista Doll: no, thanks. Also, the difference from Anmi's original chades to the actual animation chades saddens me.
Fate/Kaleid Liner Prisma Illya: I don't know, maybe? Actually I might actually end up watching this... I always have hope for Shin Oonuma's direction, even though I've had a couple letdowns in the last few years (mostly C3, really, that one was bad).
Free!: I'm gonna check the first episode out at least, because it can't be worse than the crap KyoAni has put out in the last few years. It's going to be on par at worst, just with the fujoshi in mind instead of their usual target. Which means it's going to be the perfect base for flaming with the worst kind of moetards around, those that ended up enjoying even Tamako Market.
Gatchaman Crowds: Gatchaman. Kenji Nakamura directing. Script by Oono Toshiya. Gibeplox. Anime of the season potential.
Gin no Saji: Hiromu Arakawa doing her version of Moyashimon. Arakawa haters will hate, but it's good stuff. The director worries me a bit, but the bad stuff he's done was the original source's fault rather than his, so I'd say it can come out well.
Kami-sama no Inai Nichiyoubi: uhm. The premise is pretty original. I don't know anything about the original work, either. Madhouse working on it means that is should be backed up by a proper technical side at least. I'll probably watch this.
Kitakubu Katsudou Kiroku: nah, not my thing. Skipping.
Love Lab: ditto, skipping.
Stella Jogakuin Koutouka C3-bu: I'm not interested in this, but I might check it out to see if what's left of Gainax, now that most if not all the good people left the studio, is any good anymore. I fear I'm going to kill any leftover hope I might have left.
Uchouten Kazoku: THIS THIS THIS THIS. This has SO much potential. The original novel is by Morimi Tomihiko, the author of the novel upon which Tatami Galaxy was based on, too. The original chades is by Kouji Kumeta (szs), which I quite appreciate, and it was adapted pretty well for the anime. P.A. Works is a good studio as far as technical side goes, and the director has collaborated on many good shows, so I have high hopes all around. Anime of the season potential.
Watamote: the manga is good stuff (social NTR lol). I have NO clues about the anime since we don't even know who's going to work on it and what's the format going to be and so on. We will see. Depending on how things go, it could be one of the better shows around (the opposite could be possible too).
As far as sequels go, definitely watching the Genshiken sequel. I'll wait before checking Monogatari SS, but I'll eventually watch it too. I'm undecided about TWGOK S3, because S1 adaptation was so and so, S2 adaptation was bad and I dropped it, but the arc that's going to be covered in this season is very good, so it might be worth it, though based on the first two seasons it still won't be as good as the manga. The others are sequels of things which I either dropped or never bothered with outright.
