Well manga costs less if it's unsuccessful, so they're more willing to take risks with it. The price of modern animation is staggering, generally speaking they'll only make an anime if they consider it a sure fire hit. Also the otaku market is so unbelievably conservative and set in it's ways that they frequently wont accept an anime that deviates from the norm. If it's not Moe or fanservicey you'll have a seriously hard time selling dvd's in japan.
The international market is even worse in many ways. The majority of western fans are only interested in shounen anime like One Piece, Naruto and Death Note and are notoriously crappy at buying dvd's. In one case an anime that got full release in the uk sold exactly 3 copies.
Any way. Any season I generally pick a handful of anime to watch and then whittle it down to a few that aren't totally shit.
This season "Attack on Titan" and "Flowers of Evil" are the two that are most likely going to be the best. Both of them are adapted form really interesting manga and are beautifully fucked up and disturbing in their own way.
