If anime as a genre brings to mind fanservice, childish boob-humour and a bizarre obsession with characters that have a single emotion they express every time they open their mouths, then leave it to this film to add some variety to the pallet.
While anime has examples of all styles and genres of film housed within its animated shelves, there aren't a lot of films that bring a serious tone, thoughtful plays on philosophy and stunning animation, while avoiding the cliche's of anime. This is one of them.
Beginning strong, the film immediately sets out gorgeous visuals with a high-key pallet and beautifully envisioned world. The attention to detail in architecture and environments will encourage the use of the pause button, while the complexity of background animation is at such a level that the sheer number of moving characters approaches that of a live action film. This level of work is rarely seen in animation and is worth applause on its own, not to mention the beautifully coordinated combat late in the film.
Characters are written to be fairly simple, but in complex circumstances. This dedication to simplicity, at times, struggles to progress the characters despite time moving fairly quickly at times. Ariel, in particular, is barely developed in spite of the story's scope containing his entire life. Other characters are deeply wounded by their circumstances and have decisions to make regarding the road they will follow afterward. At times these wounds are gut wrenching but sadly aren't utilized to their fullest extent in developing the characters involved.
If watching the english subtitled version, there are some things lost in translation, that could result in some confusion. The jumps in time are also not the easiest to follow, which doesn't help the pacing. In the end, however, they successfully blend a heart-felt story of love and maturity and family together with a fantastical setting with hints of deep lore and history that satisfies on a higher level than the vast majority of big-budget films being released in current days. The animation is spectacular, the story is thought-provoking and the world is entrancing.
