The aforemented, and titular, advice is especially valid. Laika Animation and director Travis Knight’s Kubo and the Two Strings is a well-told story about a destiny-d storyteller that rewards those punctual and attentive enough to watch a movie from its start through to the very end.
Yes, they even let you in on what the title actually means if you watch attentively. Watch. Attentively.
That said, moving on….

Debut director, but veteran Laika Animation animator, Travis Knight keeps the film’s focus tight and aimed at Kubo’s quest for three pieces of legendary armour to stop, as per our subjective interpretation, the creatures stalking him. The film hits all three pieces and culminates, much in a geographically circular way, in a showdown with the Moon King. That also being said…

The film’s story – and the story thereof a culmination of Knight’s childhood fascination with Japanese culture and co-screenwriter Shannon Tindle’s dinnertime pitch some years ago – deals with themes such as the need for family, loss, parental disappointment and the search for stand-ins thereof: essentially the importance of the family unit. From the start until the end. This forms the core of the film and there are little divergences therefrom.

The voiceover performances centre around the trio of Art Parkinson’s Kubo, Charlize Theron’s Monkey and Matthew McConaughey’s Beetle. That being said, it is here that the film behaves more like an out-and-out team-up affair as each has issues, culminating in resolution, with the other over the film. That being said, and reverting to the screenwriting commentary somewhat, there is a distinct feeling of culmination for all three as Beetle regains his memories, Monkey succeeds in helping Kubo find the whole armour and Kubo defeats the creatures stalking him. Ralph Fiennes is also there in a not-entirely-distinctly-Ralph Fiennes-y voiceover. Again: Pay Attention.

The score, by composer Dario Marianelli, is a mix of a closer-to-Japanese regional and classical music. In keeping with the restrained epic feel of the film, the music is similarly present but never overpowering. The George Harrison-penned original song, While My Guitar Gently Weeps, performed by Regina Spektor is equal parts haunting and soothing and worth listening to, both with the end credits and on its own.

Whilst stop-motion cinematography requires more dissection than is the case here, cinematographer Frank Passingham uses an interesting mix of perspective-y angles that convey the size of different obstacles – à la the opening waves, the size of Kubo’s origami figures amidst an audience, and, of course, the skeleton scene – in a miniature-heavy film.
More simplistically than Kubo and the Two Strings, or really any film warrant, Kubo and the Two Strings is a focused family-themed animated film that cuts through a supernaturally-imperilled feudal Japanese backdrop. If you’re the sort of viewer, à la Travis Knight, to whom that synopsis appeals, you’ll have already gone and seen it. If you’re a fan of focusedly-told stories with little dithering, go see it too.
