KLK is consistently a blast to watch, but there's very little meaningful development (the status quo has barely changed since the first episode, about the only thing that's changed is Ryuuko knows who killed her father now) and Ryuuko and Satsuki are both kinda boring, which is a shame because most of the supporting cast is great.
Winter has been pretty dull so far, Space Dandy has been good but not as great as hyped. There are a bunch of other decent to good shows (Noragami, Chuunibyou, and D-Frag being my favorites I guess, though Nisekoi is really nice to look at too) but nothing has really impressed so far.
