I liked it.

I didn't think it was great, or even very good, but it entertained me and I felt happy after watching it. It was fun, summery, and Ayu looked super natural in it. She wasn't overacting or oversinging; she was just being naturally Ayu like she would at a concert. That's what I most liked about it.
I was greatly annoyed by her dancers, though.

The mics on them didn't bother me, it was their "WTF????" dancing. It was like the most silly dancing I have ever seen them do. I couldn't stop laughing whenever I saw them dance!! And the second Shuya jumped in and made that CRAZY expression I nearly peed my pants.
