Just some thoughts from me regarding a few from the new season that I've now seen.
Definitely keeping on Another; I liked the premise (however outlandish) and the stylisation that P.A. Works have adopted. Having not read the manga or the original novel it's based on (which I consider a good thing), and the added ambiguity, it's difficult to say how this'll transpire, but that's part of the appeal of an anime like this.
I went into Zero no Tsukaima F reluctantly in account of the previous season (it's very indicative of its quality when the only thing I can literally remember, aside from Rie's squeals, is how lacklustre it was), only to be pleasantly surprised by how much I ended up enjoying this. It's nothing special, nor attempts to be, and it helps that I don't hate the characters. It also seems that there's actually a plot to speak of, which is good. I was planning to watch this at some point, regardless of whether it'll be weekly or not, but time permitting, I might stick with this while it's airing.
The same goes for Aquarion Evol; I can't say the original series was all that great (I can only recollect how cocky the protagonist was), but this turned out to be reasonably enjoyable, and the animation was pretty damn good. However, given how much I'm following at the moment (nearly 30 series!), I think I'll leave this one for a marathon once it finishes.
