I think it's a funny anime that you can watch a lot of times because It will make you laugh always (or at least this is what happens with me). It seems a stupid anime but it has it's charms.
It's true that the story isn't fascinating but this is because at the end it's a an comic gags anime and I think that it don't pretends to have an story. The characters are funny and I think that everyone of us that is a lover of anime, manga and video games will feel identified with Konata.
I recommend it for people who likes anime with Japanese humor.
PS: I have to say that the opening is GREAT!
