Through a chain of exciting and dramatic events, this TV series follows struggles and efforts of a group of best investigators across the world, under the leadership of Louis Daniel, a French police officer, as the team follows each small detail, in order to reveal the hidden truth and sue the suspect.
There's potentially a very interesting show about cops from different cultures, with different methods of policing, learning to work together. Based on the pilot Crossing Lines just treats all that as window dressing for the same old, same old.
Crossing Lines tells a satisfying story of the hunt for an international serial killer, but it is so clumsy in its efforts to set up an emotional payoff that it probably shouldn't have tried at all.
Designed for sales in as many markets as possible around the world, it's a financial consideration more than a creative venture, and it's a boring one at that. Don't bother.
Though constructed from off-the-rack tropes and predictable dialogue, the show also keeps moving forward, causing its characters enough trouble that you feel compelled to stick around at least to see how they get out of it.
