Synchronic

Mackie and Dornan do their best with their intrepid characters (though Dornan is sidelined for much of the time), while the women have little opportunity to register as interesting characters.

Less successfully realized is the bond between the two heroes. Dornan is not as badly miscast here as he was in Fifty Shades of Grey, but Dennis is never a terribly engaging character.

A sci-fi inflected story...this might be the least successful of the creators' films, it does look a bit on the cheap...the initial idea is really interesting, but when you get down to it, it's a straight-to-video B movie...

By turns gloomy (heavy shadows, ominous score) and deeply goofy (see plot premise), the film is underpinned by some easygoing chemistry between the co-leads, Anthony Mackie and Jamie Dornan.

Shot with a doleful urban grittiness, Synchronic suggests one of Philip K Dick's narcotised mind-benders spliced with the existential gloom of Scorsese's Bringing Out the Dead.

A smart indie sci-fi which has much to say and some great ideas, all wrapped up in a designer-drug-based premise that makes it sound less interesting than it actually is.

Benson and Moorhead have still created a grim, uneasy thriller with genuinely hair-raising moments.

Benson and Moorhead have a visual style full of creativity and flair... Sequences in Synchronic are immersive and suitably hallucinatory.

There is humour in the screenplay, but also serious socio-historical ideas about the way a young black man is seen across different eras.

The effort to construct another inventive sci-fi concept is appreciated, but the final product is underwhelming.
