I bumbled into this anime while searching for a vampire anime. What I found instead was simply... fun
Don't expect a great (or even coherent) story. I still don't understand much of the logic! Plot holes are simply filled with great music, and ambiguous characters are covered in plot armour. Some scenes are spoiled a bit by the occasional use of 3D, which I felt didn't blend well. There is much that one can criticize about this anime... and yet... it's still fun.
Visually this anime is eye candy with sexy vampire musicians and homo-erotic subtext. The voice acting and singing is stellar, and characters look great both on and off stage. It's truly all about the music and ultimately thats all an anime like this needs to be enjoyable. Its great for those times you'd prefer to switch off your brain and let your foot tap to the beat of the music. Even if you are clueless about J-Rock (like wtf is Visual Kei?), it still holds high appeal. The main aim of this anime is to entertain... and damn, it does it well.
Overall I enjoyed it for what it offered. 7/10
