I dropped GA after I figured out it was a poor effort to try and match Hidamari Sketch, a far superior series. Not that GA was bad or anything, it was just trying way too hard.

Speaking of which,

 

Another great 2009 opening.

 

Hey, it aired in 2009, thus it's a 2009 opening.

I liked Eden of The East's opening theme myself. Loved the choice of music.
