These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Tales from Earthsea
Awesome Music: Therru's Song is a sad, beautiful, and lonely melody. Hearing this amazing song made the watching the film worth it.
Faux Symbolism: Sparrowhawk has been compared to Jesus, Cob to Satan and Arren to mankind flaws and all.
Narm: No matter your opinion on the movie, the scene in which Cob's arm is dramatically cut off definitely qualifies as this.
Any time Arren gets angry. He comes off like an Emo Teen trying to look tough.
So Okay, It's Average: What makes this so disappointing is the strength of the source material and that this is GHIBLI we are talking about. They just don't make mediocre material.
Not only that, but many plot points introduced in the film's opening are dropped almost immediately after. Dragons returning, the death of the king and the implications of a war on the horizon all seem like they'd be major plot points later but are never brought up again.
