I'm sorry, but I was never a worthless moeblob with no personality.
The show went absolutely nowhere. The characters went absolutely nowhere. They all had their own little gag, and it was simply repeated endlessly throughout the series - and that becomes the summary of their entire character. Ooh, Konata likes anime too much! Tsukasa's an airhead! Minami has small breasts! Hiyori draws manga! LOLOLOLOL!!!
Even with the potential Kagami brought in, someone with at least a hint of personality, they went absolutely nowhere with it, like with that keychain incident.
The comedy? Worthless. Let's set up a joke: Somebody does something normal like, ooh, bites on their pencil when they're thinking. Someone else asks "Hey, <moeblob>, why are you biting on your pencil?". The person replies "Oh, I guess I do this when I'm concentrating! Haha!". That's the joke. Horrible timing, bad execution, and they overexplain everything. Not to mention the segments for each show are completely unrelated to each other, which is just lazy.
Lucky Channel was the only segment worth watching whatsoever because there was some progression and two somewhat interesting characters and an interesting satire, but they in no way redeem the show's massive failures in characters and humour.
