I watched PGSM in it's entirety before I finished the original anime or the manga. So I encountered Sailor Luna before I properly knew who Chibi Moon & the outers were. Which has probably shaped my opinion but Sailor Luna is one of my favourite senshi (third after Moon & Venus).
I thought it was a great idea, I loved the transformation, I loved the attacks. I enjoyed the light heartedness she provided among all the drama.
I would love to see her in anime form & using the unused attacks Naoko had intended her to have. I know that's likely never going to happen though.
