A coming of age story involving young love and a mysterious music, coming from a crystal radio left as a memento by an absent father, that leads a young heroine deep into a hidden world.
Generally I steer clear of your bog-standard anime, but Children Who Chase Lost Voices (which we caught on Netflix) resonated with so much mythic gravity and such strong story writing, that it begs a second look. I gained the sense of startling depth in world building with a solid mythos. Though on the outside, this is very much a young girl's coming of age story and her dealing with her absent father, it is also very much a tale about how one comes to terms with loss through death.
While I'm no fan of cute critter side-kicks, Mimi the cat was adorable while being suitably pesky, and her own story arc was apt, and I won't say any more for fear of spoilers. Characters all have strongly developed narrative arcs that interlace well, and have satisfying conclusions.
The production is exquisite down to every last detail, and the plot gradually unfolds, taking you from the everyday to the absolutely downright fantastical to the point where I was watching with the gooseflesh creeping up my arms. I will add that up until now, my experience with anime has been (mostly) limited to a few Studio Ghibli films, so I don't have much of a repertoire to draw on in order to make comparisons save to say that this compares favourably to the likes of Spirited Away and My Neighbor Tortoro.
Also, I really need to watch more quality anime, so if you have recommendations, please feel free to make them.
