This will be (extremely) brief summary of the my current first impression for series;
Hana-saku Iroha = Oooooooooook, wonderful visual, wonderful music. But, morning drama storyline which is done 100 times before. I don't think this will be anything that is memorable
Nichijou = 'Too good to be true' quality for a mere astral not-so-slice-of-life comedy show, expected from Kyoto Animation. However, it was boring than funny most of the time.
Steins;Gate = Nico Nico quality is shit, but most impressing one so far. I was so focused during the entire episode.
