Hi, another guy who'd seen your post :P
Checking your blog, I'm guessing why you have quite a low impression of this season is due to mostly watching the ... lesser quality shows
Aside from the shows Archon_Wing and Reckoner had mentioned (all of which are good) , I would also vouch for Sket Dance, even if the first episode wasn't necessarily perfect, the show is very promising, considering that the manga is quite charming and has great drama, and since you happen to have liked Letter Bee, you might want to give this one another look.
I'm of the opinion that this season is actually quite solid, though I'll coincide that there hasn't been a sign of an ''excellent'' show as of yet. But everything seems to be going towards a good direction thus far.
You might also want to give Dog Days a second look, since the second episode is mostly an action episode, to readjust your view of the series. While it's certainly a shame the show seems to refuse to have sense of tension or threat, it's still a fun show that might work as a bit of decent fluff.
