I'm just going to come out and say this. Lucky Star was boring. It was a show about a group of girls that sit around and talk about stuff. It's supposed to be funny and cute. They wrote it so you could relate with the characters. It addresses everyday issues. That is the entire idea of it.
I couldn't get behind it. I have a different sense of humor and because of that not much of what they said was funny. And without laughs, what do you have? An incredibly boring show! Plus it didn't help that they tried to make Konata into a nerd's fantasy girl. It really just pissed me off.
But, with all that being said, it wasn't a horrible show. I disliked it, but I'm sure the general population would like it. And they do. It's exactly like Azumanga Daioh. Watch it if you want to laugh.
