Really unique tv series made in United Kingdom in 2016 year. If a tv series can manage to keep me hooked for the whole time, that's impressive. Very entertaining tv series, probably the most popular tv series from Colin Teague. Dark Heart - Season 1 is definitely the type of tv series that you can watch several times and always see something new, interesting. I didn't notice anything wrong in Dark Heart - Season 1. Believe me, for a long time after the end credits, I felt confused.
