* AnimationAgeGhetto: Somewhat. It's recommended ages 5 to 7 on Netflix, despite the whole "vikings attacking and murdering an entire village" thing.
* AnticlimaxBoss: [[spoiler:Crom Cruach. Despite being an ancient Celtic god who destroyed Aisling's entire family (and possibly species), it gets about a minute of screen time and is promptly defeated by ''a piece of chalk''.]]
* AwesomeArt
* CrowningMusicOfAwesome: The entire soundtrack is great, courtesy of Bruno Coulais and Irish band Kila, but Aisling's Song is particularly noteworthy and regarded by some as the film's high point.
* EnsembleDarkhorse: Despite getting less screen time than Brendan and Aidan, Aisling is by far the most popular character in the film, even finding her way into [[http://www.empireonline.com/features/50-greatest-animated-characters/default.asp?film=45 Empire's list of 50 best animated movie characters]]. Compare the [[http://upload.wikimedia.org/wikipedia/en/a/ac/The_Secret_Of_Kells_Promo_Poster.jpg original theatrical poster]] to the [[http://www.imdb.com/media/rm4181888768/tt0485601 post-Oscar one]]. She also had the honour of [[http://www.youtube.com/watch?v=ZtHXICLmaW0 going to the Oscars in 2010]] when the film was nominated for Best Animated Feature.
** WordOfGod says [[http://whitefangkakashi300.deviantart.com/journal/There-and-Back-Again-387372034 here]] that Tomm Moore's thinking of doing a short film on Aisling or Pangur Ban, but he's hesitant about it because of people's head-canons.
* JerkassWoobie: Abbot Cellach [[spoiler: post-attack.]]
* {{Mondegreen}}: What Brendan prays on the stone in the forest. The subtitles say "Oh no, it's hard enough," one can hear it as "I know eternal love," and the DVDCommentary mentions that it's a prayer in Irish, which doesn't make sense with the English subtitles...
** It's the opening line of the Lord's Prayer in Irish: "Ár nAthair atá ar neamh...". The subtitles on the UK DVD just say ''[Prays in Irish]''.
