The serie is not about the most « notorious » criminals but the most wanted and this is the good point of the documentary. Not all episodes are equal (Number 1- Ismael Zambada- is not the more interesting and Number 4- Semion Mogilevich- look like a never-ending coarse trailer), but all of them use a lot of great (and bloody) archival shots and documents how these criminals managed to escape the authorities.
The last episode- Matteo Messina Denaro- takes place in the same location (Sicily) all 45 minutes long but keep you on the edge of your seat.
