Sé quién eres

From the beginning a story-line that draws you in and holds you spellbound. Later on, it does get complicated - if you're the kind that likes involved mystery plots then you'll love it.

It is a dark piece and it is true that one can't actually warm to many of the characters – even the victims usually have their dark side.

I like the skillful changes of pace throughout, you're never more than a short time away from the next gripping high point but there are plentiful pauses to help you assimilate what is going on.

I thought most characters were acted very well indeed. The main character Juan Elias played by Francesc Garrido I've seen described as "wooden" but I thought that this was actually a deliberate reflection of his inscrutable screen persona. As he is faced with more challenges later in the series I think you can really see the subtlety in how Francesc portrays him.

Like many I was very disappointed to be left hanging at the end of episode 10. I speak Spanish and soon discovered that in Spain there were another six episodes available. The story-line up to the last episode in the UK did not make it a natural moment to break the series.

In answer to previous questions I can confirm that if you purchase the box set of DVDs from Spain, with the title and packaging in Spanish – containing 6 DVDs you will get all episodes 1-16.

The UK version contains fewer CDs and 10 episodes. To be clear – the Spanish release does not, I repeat, does not have English subtitles. I found the dialogue and the plot a bit too fast to follow comfortably in Spanish as I am not a native speaker, but there are Spanish subtitles intended for the hard of hearing. I used these and it made all the difference. No difficulty in following the dialogue. I doubt that beginner or intermediate Spanish would suffice.

The 6 disc version is available on some Spanish websites with delivery to the UK. Or try ebay - search for 6DVD set Se Quien Eres.

Fabulously layered script, unpredictable till the end, evolving characters, superb casting with briliant Blanca Portillo (Almodovar's Volver). I wouldn't like to be a member of that familly though...

I'm at a crossroads with this. I tuned in to hear some Spanish and got quite hooked on the story, as there was some real intrigue and the potential for a good yarn. However, I'm just over halfway through the series and it seems to have deteriorated into a 'whodunnit' with so many characters and possible motives being thrown at the audience, through its time shifts to before and after the crime, as to become quite tiresome. It's a shame, as there is much good about the show, not least some of the acting, which is excellent; but as others have pointed out, it badly needs an edit to condense it down to a more manageable duration. It takes real skill to draw out a story for as long as this without losing the audience's attention and in this viewer's case I'm not sure I care enough any longer to find out who did it. I've picked up a few handy Spanish colloquialisms on the ride so far, though, which I'll put to use on my next Iberian foray.

Really enjoyed the episoades, seen them all in one week, couldn t stop watching. Great job, actors, performing. Spain, keep up the good work!

Really enjoyed the first 10 episodes albeit annoyed with the BBC that originally their website suggested episode 10 was the series finale. Glad that they have now clarified on the website " When will the remaining episodes of I Know Who You Are be shown? I Know Who You Are will return to BBC Four later this year. The programme was originally produced as two seasons, however, its Spanish broadcaster subsequently decided to show both together as one long season. BBC Four is showing the final six episodes as series two. We'll update this FAQ when we have more information." http://www.bbc.co.uk/faqs/i-know-who-you-are
