I didn't find any part of this series slow. Its builds perfectly. Its frightening, sadistic, horrible and real. Just incredible.

Welsh TV for many years was something to be scoffed at, programmes made for a small audience, but generally forgettable. Then came Hinterland, then Requiem, Keeping Faith, and now Hidden. Welsh TV drama has become something we are now hugely proud of. Forget Scandi Dramas, Wales is now the place for dark, hard hitting drama.Hidden is very dark, and it hits hard. It may be a little slow to get started, but once it gets into its stride it is accomplished, compulsive viewing. The show has a realism to it, which at times is disturbing realistic, the pain and trauma are shown for what they are, harrowing and tragic, not sensational or glorious.It gets better as it progresses, and after some real shocks you get a gripping finale, which really satisfies. Brilliant performances throughout, the acting is of the highest order, Sian Reese-Williams, Gwyneth Keyworth and Rhodri Meilir are all worthy of a mention.Bravo BBC Wales, keep giving us these incredible stories.Loved it! 10/10

This series, set in North Wales, opens with the discovery of a woman's body... it is clearly going to be an unusual case; she died recently but was reported missing several years previously. Clearly somebody had kept her hidden away all that time. Detective Inspector Cadi John, who has recently returned to Wales to look after her elderly father, is put in charge of the case. While we see her investigating the case we also follow the kidnapper as he sets about getting a new young woman to keep locked in the remains of a derelict out-building at his remote home.This series proved to be rather different to what I expected; mostly because the kidnapper was identified early on. This didn't reduce the tension though; if anything it drastically increased it as we see him kidnapping another woman. One episode was devoted entirely to her situation at the kidnapper's home and to his strange family life. He lives with his domineering mother who knows of his proclivities but doesn't help his victim escape and his daughter... presumed to be the child of the dead girl. This single episode was incredibly tense; more like a horror than a drama as we just wait for something bad to happen. The general feel of the series is fairly downbeat; watching this one would think Llanberis is a rough area to be avoided rather than a tourist-town in the heart of beautiful Snowdonia! The cast does a fine job with Sian Reese-Williams impressing as DI John; Rhodri Meilir was genuinely disturbing as kidnapper Dylan Harris and Gwyneth Keyworth was equally good as his latest victim. Young Elodie Wilton also put in a fine performance as Dylan's daughter and Gillian Elisa is suitably unpleasant as Dylan's domineering mother. Overall I'd certainly recommend this to fans of crime drama looking for something a little different.

I can't believe the police never put that CCTV photo they had out to the public or at least shared it with the 2 uniforms who visited suspects house and never shared the photo to them or the rest of the police force. All dragged on a bit. plenty of padding in theses series.
