YMMV / Lullaby for a Princess

• Alternative Character Interpretation: The song is about Celestia's remorse for not noticing (or for ignoring) Luna's problems, going so far as to claim she did nothing. However, in the animation, there is a scene where Celestia does try to talk to Luna, only for Luna to instigate an argument and shut her out. Was that really the only occasion Celestia tried to help, or is it possible Luna refused Celestia's help before that incident, and Celestia is blaming herself for giving up? After Luna transforms, we see Celestia listening outside the door and sadly walking away, which may imply she didn't know what else she could do at that time (and in her defense, if Luna wouldn't talk, there may not have been).
• Heartwarming Moments: Meta. 5 years after making the animation, WarpOut revealed that the reasoning for the silence until now was due to losing his job and having to go on a job hunt. Now he is married with a 3-year-old daughter and his family takes priority. While he makes no promises about making another project like this, he wishes that he could do so in the future. The replies are filled with comments wishing his life all the best and are simply relieved that he is alright.
  • The scene where Celestia tucks Luna to bed with her magic is one, but it quickly turns into a tearjerker.
• Tear Jerker: Fans have long considered Woona to be a Woobie, Destroyer of Worlds, due to being trapped in Nightmare Moon's mind (and the moon itself) for a thousand years. But the lyrics make it clear who the real Woobie is: Celestia.
  • Two verses in the middle make the point so well it's like being slapped:
    Soon did that pony take notice that others
    Did not give her sister her due
    And neither had she loved her as she deserved
    She watched as her sister's unhappiness grew
    
    But such is the way of the limelight, it sweetly
    Takes hold of the mind of its host
    And that foolish pony did nothing to stop
    The destruction of one who had needed her most
  • Without the Shakespearean language: Celestia enjoyed the spotlight. She noticed Luna going down a dark path, but did nothing out of fear of losing that spotlight. Luna wasn't the only attention whore in Equestria...
  • The scene with Luna's empty bed can be one.
• Visual Effects of Awesome: HOLY CRAP!!! The animated music video has absolutely gorgeous art and stunning effects, and does a wonderful job of conveying the emotions present in the original song.
• The Woobie:
  • Poor Luna, neglected both by her subjects and by her own sister.
  • And poor Celestia, realizing her mistake, and knowing she can no longer do anything to get her dear sister back for the next thousand years. She might have been blinded by the glory and attention she received, but deep down, she has loved Luna the whole time.
