This film is kind of one of those movies about nothing in particular, sure its narrative is strung along by the worries and growing pains of its female teenage protogonist; but you could easily miss 5 or 10 minutes at a time and still understand perfectly whats going on.
However the simplistic beauty is all part of the charm. The characters and wonderfully drawn animation provide a powerful, and somehow nostalgic sense of place and time. To some degree, we've all experienced the the feelings and emotions this film conjures so subtly throughout its runtime.
Be prepared to smile, laugh and probably cry, over this sweet and heartfelt snapshot into the life Lady Nikuko.
