Crossing lines brings an international flavor to the TV Crime Scene. It provides not only the chase and capture for the viewer but also provides enough suspense to require the viewer to also think! This the type of crime show that many of the U.S. do not offer and for those whom really like mysteries find when viewing British TV. While it does misinform those with a lack of knowledge about the workings of the International Court the fictional group does its job showing that crime is an multi national problem. A more feasible scenario would be that the fictional group is a part of Interpol. I give it rating of 7 based on the following: Good Imaginative writing. Good Acting. Good Photography. Enough Action without becoming boring.
