I really don't understand how you're associationg "singing" with "fluffy," but whatever. Fact of the matter is, if Basara had shot up his enemies, it would have been the run of the mill everything that's been done before, and all things considered in context, the Protodevelin were so strong that the 7 fleet was way outgunned, even with reaction weapons.
Telekenetic/chi/whatever powers are nothing new to anime, aren't localized to any one genre, and are quite proficient within the culture. It's just as silly as complaining about Newtypes in Gundam, Overmen in Votoms, or Jedi in Star Wars.
