Yoshiro Togashi’s Hunter X Hunter is known for its complex plotting and subversion of Shnen tropes, which makes it one of the most timeless stories in the genre. The 2011 Madhouse adaptation does justice to Togashi’s story and artwork, leaving its audience craving more. Phantom Rouge is the first of two Hunter X Hunter films, and while it looks like HXH, it lacks the quality of storytelling and emotional payoff characteristic of the series. Non-canonical anime films are a great entry point into established franchises, but Phantom Rouge does a horrible job of distilling Togashi’s brilliance into its 97-minute runtime.
