When I started watching this, the time line ticking back took a little getting used to but by the end of the first episode I was hooked. This is a very compelling, brilliantly original approach to a whodunit drama. The plot is multi layered and enough is served up at each stage to make not binge watching the next episode almost impossible.
The acting was solid in particular Richard Dormer and Isaac Taylor, with Jodi Balfour proving she really is a standout after her notable previous performance in the excellent adaptation of Max Collins's Quarry.
The directing is subtle, slick, and atmospheric where needed without being over egged.
I highly recommend Rellik. If you enjoy the likes of Luther, you will love this. Allow yourself the full first episode to settle into the style of the writing & time line structure and you will be rewarded by this gem of a series that will keep you guessing through it's twists and turns.
