Liaison is a rather predictable Western spy thriller.
It adopts the simplistic formula of everyone opposed to the West being "bad", whilst the West is painted as good and virtuous. Syria, is painted as the bad guys. This ignores inconvenient facts. For example, the West's uninvited presence in Syria, being largely illegal, under international law.
Moving beyond the propaganda, the story is your standard spy thriller fare, with a dollop of alarmist rhetoric about super hackers and how the authorities are there to keep everyone "safe". Even when they are taking a dump, on your basic human rights.
Off settings this nonsense, is a bland spy soap opera about two people and how their past mistakes impact on the present.
Acting is of a high standard, it s just a shame they could not come up with an original story of the same calibre.
