I said this before but I dont know if it was on your watching list for last season but Tsuritama is definitely worth it. Weird, quirky but funny and has heart. Plus some of the visuals harken back to Kuuchou Buranko which was directed by the same guy.
I've got a few shows that I want to finish first from the previous three seasons before diving into the new season. I tried watching Natsuyuki Rendezvou, but my reaction is pretty much the same as yours. I got nothing out of it. I also want to watch Sword Art Online when I've pooled up enough episode to see what's the hype is all about.
Right now the only thing Im watching is Arcana Famglia. Not much for summer has interested me so far. Im trying to catch up from last season, Tsuritama is quick quirky and fun. Also want to try Hyouka. What are you watching?
Also watch Kuroko's Basket when you get a chance. Despite being a low budget anime, this one actually has a pretty engaging story. Jormugand and that one have been my weekly regular fix for the time being while the rest are piling up for later watch.
