At the outset, this film may seem like a slow, perhaps heavily cerebral drama without a wide appeal. However, dig a little deeper, and you'll discover that Who You Think I Am is actually a thrilling, sleek and deeply enthralling watch.

With a dynamite lead performance from Juliette Binoche and arresting direction from Safy Nebbou, it's a slow-burn thriller that you really won't want to take your eyes away from, as it continues to surprise with regular twists and consistently thought-provoking themes.

The overall premise is simple. Who You Think I Am plays out as a romantic drama between Juliette Binoche, who pretends to be a younger woman online, and François Civil, who we almost only hear by voice and see by text message.

The story therefore looks at the practice known as 'catfishing' (pretending to be someone else online). However, rather than simply looking at the morality of the practice - which is a fairly straightforward debate - Who You Think I Am is a film that takes a really wide perspective, and seeks to understand and discuss a lot more about how this kind of situation comes about.

As a result, though the inevitably doomed online relationship is agonising to watch unfold, the film's most interesting suit is its perspective on female emancipation and liberation - using Binoche's middle-aged character as an example of how women are pigeonholed into roles to conform with by the pressures of society.

In portraying her character's desire to break out of that role, Binoche gives a powerful performance that blends an inspiring and passionate show of female independence with a striking sense of unhinged obsession. As a result, while you certainly sympathise with her character and her motivations throughout the story, that tinge of darker, obsessive personality makes her an ambiguous and often unpredictable lead throughout the film.

And that's where Who You Think I Am is really able to stretch its legs as an all-out thriller. It certainly doesn't have the pacing to be considered your average thrill ride - playing out at a very patient tempo with intimate dialogue scenes the central focus - but there's a bubbling air of cagey tension that grows and grows throughout, which makes the film a captivating watch right to the finish.

Director Safy Nebbou does a brilliant job at injecting that tension and dramatic eeriness into the mix throughout. He's able to make sure the film retains its slow, pensive atmosphere (which allows its dramatic themes to really come out), but also creates genuine excitement with a sleek, modern visual style and a powerfully tense aura in every scene through the film.

The film is at its best in the second act - where tension and thought-provoking dramatic depth work hand in hand. Meanwhile, the third act brings some shocking twists to the table, taking the story in an unexpected direction towards the finish - although it's fair to say the screenplay piles on a few too many twists in the closing stages, bringing things to a slightly more convoluted end than perhaps necessary.

Saying that, I was really impressed by Who You Think I Am. A gripping drama that works just as well as an unnerving and exciting thriller, it's a sleek, stylish film that's full of riveting and thought-provoking dramatic depth. The lead performance from Juliette Binoche is excellent, and director Safy Nebbou does well to balance the film's numerous different styles and ideas throughout.

I am always keen to watch a Juliette Binoche film. She is a proper film star who possesses a glowing screen presence. A lesser actress (can we still say that?) would have struggled with the lead role in this film because it is virtually (sic) a one-woman-show. Juliette succeeds with ease. This is a quiet little intimate film about a woman (Clare) in her 50's playing out a mid-life-crisis fantasy over the internet. Her long-term husband left her for a younger version, so she reacted by taking a young lover of her own who soon becomes bored with this much older woman. So, she suddenly decides to create a virtual younger version of herself and chooses the flatmate of the former younger lover to hit on. He has never met her but knows of her, and is conned into believing she is only 24. The cat-and-mouse game is played out just long enough to maintain our interest and we are given interspersed commentary by her as she explains it to her therapist. The scenario plays out in dramatic fashion, but then we become aware that she may not be telling the therapist the full story, and other possible endings emerge. This has the effect of distancing the viewer at a crucial stage, which baffled me at first, but, after the film ended, I believe I understood what the writer was getting at. I am a man in his 50's surfing the web for love, diversion and perhaps even re-definition. My contemporaries and I did not have the internet when we were becoming adults, so for us it is a magic landscape. Previously we were defined by our setting, family, friends, and cultural norms. Now we can be shape-shifting dramatic characters who don't have to make do with the tales others write: Instead we can create and star in our own life. A movie star from a script of our own choosing and editing. Binoche does not visibly glow in this role as much as she often does. Instead she ages defiantly. Her character doesn't actually go on an emotional journey, more a foolish escapade from which she ultimately concludes that having control of one's identity brings with it great responsibility. I liked this movie. Clare is supposed to be an intelligent lecturer, but finds herself behaving like a giddy teenager playing silly but potentially deadly games with the emotions of others. This could have been quite unbelievable, but the simple production and Binoche's skill allow us to take the idea on board. There are many high crane shots in the film which reminded me of sequences in my own dreams in which I seem to hover above the action. Seeing as the very first shot of this film is of someone nudging Clare out of a nap, then this impression that I had was possibly no accident.

Every now and again you come across a film that you know very little about but fine the premise intriguing and it more than lives up to that intrigue. Juliette Binoche - who is in pretty much every scene - is a mesmerising presence as Claire - a lonely university professor who is struggling with inner demons. To say anything else would spoil. Suffice to say, this is a film which, whilst easy to follow and you never know what's going to happen next, would no doubt benefit from a second viewing. I will definitely be watching again. Currently streaming on Netflix - this is a sexy, twisty drama/thriller that at least for me was a hidden gem. 8.5 out of ten

While this wasn't a bad film I can't help but shake off the feeling that if the genders of the characters were switched around the film wouldn't be described as a romantic drama but rather a creepy psychological thriller.

I was expecting another movie about social media but not. More about getting old and relationships in the technology era. Great Juliette like always. And you will never gues what will happen at the end.
