Paul Verhoeven's sci-fi masterpiece RoboCop is worthy of infinite repeat viewings because it satirised the 1980s more effectively than any other movie. It shot capitalism, consumerism and right-wing politics in the head and took a subtle swipe at Hollywood's increasingly action-focused values in the process.
On top of that, Alex Murphy's cybernetically-enhanced comeback is a story of triumph, the tale of a man who returns from oblivion to smite those who put him there, reclaiming a trace of his humanity along the way. The audience revels in his ultimate victory whether witnessing it for the first time, or the fiftieth.
RoboCop is also a movie laden with metaphor, from its prominent Christ symbolism to its shrewd deconstruction of post-modern society, and it takes a number of rewatches to truly appreciate everything Verhoeven has to say.
This movie is more culturally relevant and poignant than a film called RoboCop has any right to be. No matter when you revisit it, its impact barely diminishes.
