Gaichu is pretty good, but it's more about Miyazaki Aoi's performance than Yuu's one. Quiet room was pretty boring, but Yuu's character was probably the most interesting. But still I agree with the ranking so far.
I was just in the middle of constructing my own 'Yu Aoi Ranked List' when I noticed this!....haha, j/k. This ranking of her films is pretty much how I feel. I would instead put Tekkonkinkreet in 3rd place though. So Gaichu didn't make your top 7 huh? Interesting, I thought that movie was supposed to be good? I still haven't seen it.
