I'm not sure why people don't like the voices. They sound good to me.
I wasn't expecting this to be a three part episode! It was weird to start a series like this. This is of course freaking awesome, with the great animation and characterizations. Sonata is my favorite. I wish I knew what she even was. Everything is so wonderfully fast paced.
It's great to see all these great jokes. My favorite was probably when she mentioned referencing that thing she saw! That's how so many jokes are these days. The voicework is awesome. While not unique from the style of the other cartoons, still tons of fun.

Good show, but the voice acting not so well...
