Luna Review

Hi! 
Now that season 4 is just around the corner (choo choo! make way for the Hype train!), everybody are making predictions about the future episodes.
From the season 4 animatic clip we know for sure (MINOR SPOILER) that there will be a Scootaloo/CMC episode; Pinkie Pie/Apple Family; and, drum roll, more Princess Luna.
This made me think of characters, Luna specifically. What kind of princess she was before going evil? Maybe she did something worse then threat eternal night to get banished in the moon? And why do everyone like her so much?

As you may guessed, I'm going to review Luna!
First of all- back story.
Luna is the Princess of the night and Celestia's younger sister. She was the main villain in the first 2 episodes of season 1 as Nightmare Moon. She was restored back to her former self through the Elements of Harmony, and returned to rule Equestria alongside her sister.
In the prologue of the first episode we learn that she became Nightmare Moon, a "wicked mare of darkness", because her subjects "shunned" the night and slept through it, which made the young alicorn grow bitter, and she eventually refused to lower the moon to make way for the dawn. Princess Celestia harnessed the power of the elements of Harmony and "banished her permanently in the moon". Ha ha, but little did she know that Nightmare would be back in a 1000 years! Anyway, we all know the story, lets analyze.
-Personality- 
During Nightmare Night we see Luna use the "traditional Canterlot voice" - a high volumed way of speech used in order to properly address her subjects; the royal we; and archaic terms like "hath", "thy", and "thou", as well as other constructs.
Luna has quite the temper- she turns toy spiders into REAL EVIL ones, while trying to befriend the villagers. They run away screaming (who wouldn't?!), and to stop the commotion she yells at them. Way to make some friends, Luna!
Despite all that, Luna's playful, and most of the time just socially awkward or doesn't know how to behave in the modern pony society. In the "Mostly-about-Scootaloo-but-Luna-stole-her-spotlight" (Sleepless in Ponyville) episode she displays kindness and offers wise advise.
-Skillz-
-Raising the moon
-Wielding the Elements of Harmony
-Weather manipulation
-Transformation
-Dream duty (BADASS!)
In conclusion, I would say that Princess Luna is so loved because she is a very mysterious character, we don' know much about her past, or what she's currently doing. This gives the fans a certain freedom- apply Luna the traits we like. 
Gamer Luna for example, I doubt that it's possible, but hey, I just might be true, she can be anyone and anything in our imagination!

I don't know what I can add, so I'll finish here. Have a great day/night!
