It was the best film of 2009, a sci-fi romp that came with both braun and brains - and kick-started the career of South African director Neill Blomkamp in pulsating fashion.
District 9 was an incredibly impressive launch pad. But that was then, and Blomkamp's new film, Chappie, comes after his 2013 misfire Elysium - a big budget, high concept mess which he's since admitted he mucked up.
Chappie, his third sci-fi feature that again utilises the slum-filled suburbs of Johannesburg for a high-tech adventure into robotics-gone-wrong, doesn't make up for Elysium. In fact, it makes things worse.
Like Elysium, Chappie's programming is flimsy. Much of this we've seen before in better films, like the original Robocop, Steven Speilberg's A.I., '80s kids flick Short Circuit, and the cartoon caper Wall-E. It even ends with an eye-watering robotic shoot out that would make Transformers director Michael Bay proud.
Chappie references all of those films, but adds virtually nothing to them. Its threadbare plot can be easily described in one sentence: robotic police force goes haywire but a decrepit droid with an AI prototype chip could be the key to solving the problem.
