I was quite surprised when I've finished to watch CDL 11/12, because it really wasn't like people said. I was expecting something messy, but.. it turned out really good and enjoyable.
I think they kept some ideas from the original HLS setting though, but they added new things as well that could fits with CDL concert. I mean, something Hotel related but with more parties because of new year's eve.
The only thing that made me cringe was.. those damn clowns. Clowns are cute and funny, but I think she's overusing them. Along with tissue dance. Please Ayu stop it

and do something different for once.
So overall:
Yes, I liked. A lot!
