Sekai Sufuku - interesting, will check a few more
Space Dandy - noope
Mahou Sensou - occasional flash of interesting, but didn't really make any sense. I might check some more if it gets good reviews from others.
Nobunagun - wow, that escalated quickly ;p I'll check out a few more solely on the basis of the maniacal cackling while mowing things down with an autocannon. Also, how many other shows have Jack the Ripper and Gandhi teaming up to fight giant monsters ? ( this gets second place for most bizarre setting of the season ).
Nobunaga - To my surprise, not actually the same one as the previous one, but *this* one is the definitely the most bizarre setting. Nobunaga, Joan of Arc and Leonardo da Vinci team up to fight evil in feudal japan ? I thought it was ok, but not great, will probably check out some more.
Witch Craft Works - uh, I am not really sure where they are going with this. On the fence.
Buddy Complex - shows the most signs of having an interesting story from the first episode, and nicely drawn and animated. Will check a few more. Bonus points for apparently immediately jettisoning the high school setting. Double point penalty if they bring it back somehow.
