Maria Holic seemed like a good anime at first. Yu Kobayashi and Marina Inoue are some of my favorite seiyu, yuri with a trap setting is fun, and I enjoy SHAFT works very much. I thought this show will be another gem, but I was wrong.
Although seiyu performed great, the rest of the show did not fit my taste. Occasional good art did little to remedy annoying numerous monologues and perpetual nose bleeds of the protagonist along with slapstick humor. The second episode was even more boring than the first one and the art quality decreased substantially. This show reminds me of Hyakko: good director, poor writing.
Since I mentioned that I wanted to cover this series before, but will not fulfill my intention, I would like to refer you to some other bloggers covering this show.
Impz is very excited about this anime and provides good coverage with summaries, screenshots, and impressions.
Tsui’s coverage is also extensive, including many screenshots.
