15. District 9
Who says that blockbusters can’t be thought-provoking as well as action-packed? Well, 2009’s District 9 proved that both can sit side by side, not least through its imaginative plot that draws on the racial tensions and discriminatory segregation of apartheid-era South Africa. And while the hideous transformation of lead character Wikus is enough to make your skin crawl, his evolving relationship with the alien Christopher is definitely enough to also bring a tear to your eye. There’s so much going on, in fact, that you’ll need to see the Neill Blomkamp-directed sci-fi more than once to fully appreciate it.
14. Shutter Island
Although he’s mostly known for his stylish crime flicks, director Martin Scorsese turned his attention to the horror-thriller genre for 2010’s Shutter Island. The movie follows two U.S. Marshals who have been sent to an isolated insane asylum to investigate the disappearance of one of the facility’s patients. But, as you may already know, all is not what it seems on the island. Shutter Island’s watchability, meanwhile, comes from its clever use of suspense and intrigue – and that plot twist at the end is sure to have you coming back to join the dots up.
