I did not have a high opinion on Spanish thrillers in general untill I saw this. Very well told story of eight episodes. If you're into fast paced action thrillers, this is probably not for you. The plot developes over eight episodes, with each episode revealing just enough to keep watching and without giving it all away. Next to that great photography and the right (but sometimes a little confusing) mix of todays events and flashbacks. Dialogues could improve here and there, but that's basically my only critique. If this would become the standard for future Spanish thriller series, we're looking at a great future.
