The culmination of early 2000s Japanese online pop culture bubble and possibly the beginning of the decline. Lucky Star owes everything to it's influences which is proudly wears on its sleeve, with it's predecessor shows, Nico Video, gaming forums, 2chan, etc. Understandably polarizing when it leaves the circle of it's target audience but for those who've soaked themselves in the geek world of 2000s Japan, this show is so close to perfection and could never be made today with the same level of soul. So enjoy Lucky Star because there will only ever be one.
And thank you Shiraishi Minoru for creating the funniest anime ED known to man.
