the best part was the entire 2nd half when they jump into the adventure. Two details that I liked a lot were: when Novo asked not only for her guards to do the quest but Fluttershy as well, it makes you think that the queen actually changed her opinion and she wouldn't have given the mane 6 with a bad look. The other one is when Fluttershy decides to stop the spear attack in a very tense moment,making a sacrifice by putting her life in danger for resolving an unfair misunderstanding.
The ending is bit too cheesy but I liked how Novo made a killer line: "Thanks for coming and for not eating...us" and music stops. If that part was animated,that punchline would have more effect.
The average fans would love the Fluttershy and Skystar chill moments before the quests,although so many guards around them ruin a bit the fun.
