With believability being pushed too far, and the film’s direction needing a tighter pace, even the surreal visual effects and trippy weirdness aren’t quite enough to make it work.

Dornan and Mackie are adrift through most of this movie, but the heartfelt thrum of their final scene together is a testament to the intrinsic humanity of their performances — and to the grace of a visionary filmmaking team that’s capable of creating the most beautiful moments, even if they often lose sight of the most effective way of reaching them.

Through the psychedelic journeys and the blood-spattered crime scenes and the brooding atmosphere, Synchronic is at heart a good old-fashioned buddy movie about two friends who will risk all for each other.
