“Blade of the Immortal,” a fantastic, gory supernatural Japanese samurai movie from master of horror Takashi Miike, is one of the year’s most entertaining films. Based on a hit manga series in Japan, the plot has many similarities to this year’s hit “Logan” but this movie is actually better! It concerns a little girl who must convince a world-weary, immortal samurai to avenge her family. And so he does, in one of the goriest, craziest, and most epic action films in a long time. The director, whose 100th film this is, may be familiar to American audiences through “Audition,” “Ichi the Killer,” the original “One Missed Call,” and “13 Assassins.” This time he tops himself, giving us a film that is a cross between Akira Kurosawa and Quentin Tarantino. It’s longish but never dull, and is now playing in select theaters and Amazon Prime streaming.
