This anime movie spin-off is the latest instalment of a popular existing property: That Time I Got Reincarnated as a Slime started life as a novel series, then a manga, before being adapted into an anime television series. Familiarity with at least some of the previous incarnations will be essential for viewers hoping to understand this energetically baffling fantasy adventure. It’s visually striking, and at times somewhat overwhelming. Expect numerous sword-based battles, ogres, dragons, ancient curses, distractingly voluptuous supporting characters and, of course, slime.
In cinemas from 18 January
