Overview: Academy Award-winning director Steven Soderbergh plunges audiences into the suspense and drama of a resilient woman's fight to reclaim her freedom even as she risks her own sanity.

Blu ray Verdict: Shot entirely by director Steven Soderbergh with an iPhone 7 Plus camera, 'Unsane' (complete with its grammatically-challenged title) is just as likely to test your sanity as anything in the film itself.

Proving from the off that you don't need a "real" camera or even fancy lighting to make a film; just an iPhone, a decent script, a competent cast and crew and, most importantly, the will, time, money and passion to do it all, luckily for us, Unsane' has all that and so much more.

However, in truth, 'Unsane' is a wonderfully frustrating, claustrophobic and tensely insular experience that puts you firmly inside the slightly off-kilter head of its protagonist, Foy, and does a great job of making you feel exactly the way she does at every moment.

The pace is almost perfect, as we're dealt a number of blows every time we begin to get comfortable in each new situation, and the slow descent from slightly strange to straight-up sinister is a palpable and uncomfortable one.

The fact that the sanity of the hero is called into question is a great move, though it isn't pushed quite as far as it perhaps could have been, and it keeps you unsure about everything you see.

Oh yeah, and the nod(s) back to classic seventies horror, including a soundtrack reminiscent of the original 'Halloween', were appreciated as well. I was constantly on the edge of my seat throughout this gripping, agitating, intriguing and generally very entertaining thriller and I'm sure you will be also.
