Since Star Wars came out in 1977, all of the successive sequels and prequels that follows have skewed more or less towards a younger market; even The Empire Strikes Back has cheesy puppets and romantic elements which drop the ball, and from return of the Jedi onwards, it’s strictly for kids. Rogue One reverses the trend; it’s a dark, gritty, downbeat epic that tells the story of how the rebels captured the plans for the Death Star, a kind of Guns of Navarone in space. As well as addressing a number of plot holes in the original film, Rogue One feels more like a war film than a family-friendly blockbuster; parents with kids under ten should be warned that the good guys get their asses kicked here. But the formula of the original films is well-adhered to in Gareth Edwards’s one-off adventure; robot sidekick K2-S0 generates some good comedy touches, which are much needed because the storyline and characters are deliberately bleak. The introduction of a CGI Peter Cushing is regrettable, looking more like a video-game character and never resembling the original actor for a moment. But as the narrative builds to a massive multi-layed battle and a brilliant bit of business with a stuck door, Rogue One is the best entry in the series since, well, the original Star Wars itself.
