I don't appreciate skits that don't have original choreography. Like when two VOcaloid cosplayers do the well-know Love&Joy dance.. I just feel like it's simple and everyone and their grandmother has seen it before.
I don't mind dancing when there is a lot of thought and uniqueness to it. I really enjoyed watching this dance at the AB Masquerade last year, because they added twists to the choreography that pertained to Vocaloid;
