Singing and dancing:
A lot of music from the SMS musical.  Some new music like Fire and Wake Up Usagi.  They're better dancers than singers

Important Actors:

Mochizuki Yuuta plays Dracul.  Also played Tux and King Endymion.  He also was Kamen Rider J and Tyrano Ranger in Zyurangers.  He's also one of the F4 in Hana Yori Dango

Kasahara Ryuji plays Professor Tomoe

Yukimura Yoshiya plays a Death Manechas, he also plays Mandrake and a Hoshino family member.  He's slated to be one of the 4 Kings in the Starlights revision.

Takagai Nao as Uranus.  Lots of people dig her.  Mao Mita as Sailor Saturn, a lot of people like her too. Kanda Eri as Mars and Emi as Jupiter.  Gunji Ayano as Chibi Usa.

Kawasaki Miki as Le Fay.  She also plays one of the moms in Kaguya, background dancer in Shin Densetsu, Esmeroodo in BL, Kaolinite in Mugen Gakuen, and Kunzite in the Starlights musical.

Bad:
Complex, very all over the place.  Parts similar to Anza's are not as touching...

Good:
It's a lot of fun.  Miyuki's 15 only, but she has a lot of energy and makes this musical really fun.
