This is a decent movie. And that's unfortunate because the concept here is really cool and I think with better writing and less bland and uninspired directing/cinematography, this could have turned out to be a modern sci-fi/thriller classic.

The acting from the two leads, Anthony Mackie and Jamie Dornan is definitely solid, especially Mackie. However unlike Mackie's character, I didn't find Dornan's to be particularly interesting nor compelling, which is disappointing considering that his character has an important connection to the heart of the story.

The visual effects are pretty great but they could have really popped more if supported by directing and cinematography that didn't look and feel as bland as it was at times.

Synchronic also has some serious issues with pacing scattered throughout the runtime which was very hard not to notice, and at times the consistency of tone just wasn't quite there. At times it's a very dark and bleak watch, then there will be scenes that are quite funny but it just didn't work as well as it sounds like it would due to the vast contrasts.

To sum it up, it's a decent movie that is quite enjoyable and gripping enough to make you care somewhat. It's just a shame that it's not what it could have been.
