For reasons I will never fully understand (at least, I haven’t yet understood them), this show seems to be the biggest source of love/hate controversy this Winter 2013 Season. Personally, I could never hate a comedy about a bunch of quirky individuals driving each other nuts, especially when one of them is a cute goat+mafia don and another is a psycho constantly trying to murder characters from the background. That’s really all this show was before it showed it could do pseudo-serious in episode 7 and heavy serious in episode 8.
I would have called the direction for this series a bit plain prior to episode 7. I felt like I could re-piece the manga this was adapted from with little to no effort just from the anime storyboards. That said, it does the job for comedy, and the characters carry the rest. The dramatic portions were legitimately just well-done bits of heavier atmosphere; the first being intentionally exaggerated, the second being a serious story.
My current read on this show is “enjoyable quirky character comedy with some dramatic pull”. I don’t have much else to say about it because its formula really is as simple as a cast that works well together. We’ll see how the dramatic portion of the show plays out, but I’d say it’s earned its comedy chops.
