Neill Blomkamp seems to be on M. Night Shyamalan’s career path: a massively-praised Oscar-nominated breakthrough genre movie, followed by a series of increasingly maligned follow-ups.

His latest is the story of a police robot that gets inducted into South African rap/gang culture. It’s incredibly idiosyncratic, and actually kind of interesting in its oddness and the way it exposes a different culture. So there’s something to be got out of it, but it feels like a failed experiment rather than a successful realisation of a bold idea.

Still, in the homogenised landscape of big-budget sci-fi movies, at least it’s something different.
