Taiwanese director Chienn Hsiang has given his lead actress Chen Shiang-chyi a role of rare complexity in Exit, and she dominates this bleakly naturalistic slice-of-life film completely. Chen’s character, Ling, is a seamstress approaching middle age, living an isolated, alienated life with rare distractions – hardly dramatic material in itself, you might think, but the film’s accretion of small everyday events, seemingly insignificant in themselves, comes together to capture a slowly compelling sense of character and milieu.

Remember the Hitler diaries? Stern and the Sunday Times were so eager for them to be true they went ahead and published even after historian Hugh Trevor Roper had changed his mind about their authenticity. Such was the hunger for stories about Nazis. It’s still there, but Die Welt was on firmer ground when – to accusations of sensationalism – last year it published extracts from the cache of letters, diaries and memos in the hand of Heinrich Himmler.

"There is no murder in paradise" is the official line of the authorities in 1950s Russia, but nevertheless Child 44 is the blood-drenched tale of a hunt for a mass-murdering paedophile in Stalin's deathly shadow. The source novel was the first in Tom Rob Smith's trilogy about Russia during and after the Great Dictator, and Smith based it on the real-life killer Andrei Chikatilo, the "Rostov Ripper".

We’ve waited 33 years since Peter Greenway’s The Draughtsman’s Contract for another film combining romance, intrigue and 17^th century landscape gardening. Now we have one, and it couldn’t be more different.

Boasting one of the most appealingly eclectic casts in recent memory, The Salvation – from Dogme 95 director Kristian Levring – might have hoped to emulate the success of Sergio Leone's Italian-infused approach by bringing a Danish flavour to traditional western proceedings. But by relying too heavily on the tried and tested it fails to distinguish itself, meaning that the "smørrebrød" western seems unlikely to replace its spaghetti cousin in audience affections any time soon.

The burden of responsibility weighs heavily on a young man struggling to deal with his mother’s alcoholism, in Gerard Barrett’s powerful and poignant second feature. Jack Reynor, who so impressed in Lenny Abrahamson’s What Richard Did, turns in a nuanced and moving performance as a son driven to desperate measures in order to survive. Barrett empathises how difficult it can be to get by when you don’t have a regular income, or indeed plentiful cash to throw at your problems.

This shrewdly assembled, often near-monochrome actioner injects pathos from the off and mirrors the melancholic outlook of its grief-ravaged protagonist, played by Keanu Reeves, who dials down the befuddlement and proves rather endearing. Directed by stuntmen Chad Stahelski and (an uncredited) David Leitch, it's a lovingly crafted, pleasingly characterful effort that delivers impactful, imaginatively executed thrills.

The fault-lines of human relationships are tested in Swedish director Ruben Ostlund’s Force Majeure, and prove much more fraught than the physical threat inherent in the film’s glorious alpine landscapes. Its opening scenes capture a Swedish couple, on a skiing vacation in the Alps with their two young children, having their photographs taken by a resort snapper: as they readjust their poses, it seems like a search for a depiction of the perfect family.

In the past decade or so the Argentine director Lisandro Alonso’s minimalist masterworks have earned him an ardent, if particular following. With Jauja he’s moved beyond his comfort zone, by using professional actors for the first time and with more dialogue than in all his previous combined. The result is at once his most accessible film and his most mysterious, which is quite some trick. And it confirms his status as one of contemporary cinema’s great artists.

When President Obama took office in 2009, he was riding a wave of idealistic expectations of a superior brand of politics and even a better kind of world. That all looks ludicrous now of course, and one of the lasting stains on his reputation is likely to be the way the USA has ramped up its campaign of drone strikes under his leadership.
