Dangan Ronpa is one of those series that sounds good on paper, but could swing either way during its run. The BIG series this season is definitely Monogatari, which for better or worse does fairly well (as far as I know, its popularity and sales match Shingeki).
Kamisama no Inai Nichiyoubi sounds like that too, but I hear it's a novel (watch Shinsekai Yori if you want to see how excellent novel adaptations can be) so I'm definitely on board. I'm getting Jose Saramago vibes from this one… there's definitely potential here.
Blood Lad could be a trope-smashing comedy on Hataraku Maou's level, but it's been ages since I read the manga so I may be hyping myself up for nothing.
Gatchaman Crowds is a popular franchise from the 70s, so I'm curious what they're doing. There are suits, acronyms, and capital letters, so as a Tiger&Bunny fan I'm giving this a chance based on the admittedly simple similarities.
--- Update From New Post Merge ---
Maybe I'll watch Danpa Rongan, but I think I need a break from Seiji Kishi-helmed anime after Devil Survivor 2. Monobear's voice will no doubt give me bad Cancer Bubble flashbacks, too. I'll probably spend this season catching up on Railgun S, since I've always felt that the Index franchise did better when it was embracing its sci-fi side and the first season was pretty decent when it was plot-driven and not trying to push the "four girl ensemble" angle.
To be honest, most of the viewers in my chatrooms like Railgun and its "four girl ensemble" more than Index. Though I really like the sci-fi aspect of Index and I'm really looking forward to the next few arcs (having been spoiled by LN readers by now), I think Railgun builds its characters much more consistently than Index does. It's just a general feeling after having marathoned both series a month ago, but having that "four girl ensemble" in Railgun makes it a lot more focused than Index, which isn't really a flaw as much as a personal preference.
Also, Index is surprisingly annoying sometimes. kthnxbye
