I was very disappointed by this TV Series because I thought it would only recall "The Bridge" and not copy it in the smallest details. The idea of having a joint operation between the French and British police forces to solve a double murder with the corpses left in the Eurotunnel, just as the Danish and Swedish ones for the bridge, was an interesting idea. But for those like me, who had already seen "The Bridge", there was no suspense because you knew ahead of time who was going to die and why. However "The Bridge" has a better setting, I would say creepier, suitable for a chase to a serial killer. Plus, the actors deliver a better performance especially for their ironic interpretation.
