L'imposture

Beautifully shot, terrific performances and a script that sizzles with a mix of verbatim and written dialogue, this outstanding drama is a world away from most British true crime. It feels like a reinvention of the genre and is a truly compelling watch. Sion Daniel Young turns in a superb performance as Stagg and we feel every ounce of his suffering as he's targeted by the unstoppable Niamh Algar as Lizzie James. Eddie Marsan is gently terrifying as the criminal psychologist out of his depth. I've never seen anything quite like this before. An absolute 10/10.

Well written and acted. Based in 1992 London. WPC undercover entrapment Story. But all is not what it seems; The mini series of four episodes tells the compelling true story. (Some characters and events are adaptations to tell the story)

A four part series based on the tragic and brutal killing of Rachel Nickell back in 1992.

This is a dark, gritty, unforgiving drama, 4 relentless episodes that give you the horror of the crime from the point of view of the undercover Officer, it will unnerve you, it will upset you, at times it will shock you.

Parts one and two are excellent, parts three and four take it up yet another notch.

The production values are terrific, they really do capture 1992, not just the visuals, but the mood and atmosphere, the accompanying music is first rate, it adds to the story, they play some great tunes too.

I thought the acting was fabulous, Niamh Algar is the absolute standout, Treadaway and Marsan are great too.

Excellent drama, 9/10.

I can't believe the low rating this has received.

Did all contributors watch the whole series or just rate after a few minutes of the first episode?

This is a great watch especially for a fact-based story.

Gripping, intriguing, compelling and sultry.

If fits in well with general detective dramas that lead you one way then somewhere else entirely in the final scenes.

I just had to keep watching like a good book you can't put down.

It's just the opening scenes of s1e1 that didn't really seem to be needed.

Considering it's based on a true story I think the writers did a good job of squeezing as much drama as possible from the events.

But it's not perfect. There are some very slow moments and overall it might have fitted one less episode better.

Having said that, it is quite compelling and most of the lead actors were excellent.
