In my humble opinion, if you don't love Lucky Star, you hate it. There's pretty much NO middle ground. This is probably because it's basically Seinfeld
if the characters were actually likable and the weirdness was turned Up To Eleven
. Personally, I love it. The characters are fun, the jokes are good, the weirdness is pretty much why it works, and Slice Of Life
happens to be my favorite genre, so that probably helps too.
