Novelist Alex Garland wrote the screenplay for Danny Boyle’s “Sunshine,” which aimed for being an epic science-fiction film but somehow got distracted into becoming a serial killer thriller along the way.
Garland wrote and directed “Ex Machina,” which also aspires to be heady sci-fi. But this time Garland, who seems to be unable to resist the lower pleasures of genre, lets the film turn into something of an erotic thriller. But while “Sunshine” was fatally undone by its tonal shift, the mixing of genres works well in Garland’s beautiful and tense film.
