Chasing Shadows is takes an interesting but now familiar crime drama premise. Take a odd ball detective with the EQ of a house plant and a high IQ and team them up with a normal person.
Predictable but enjoyable fun ensues. The clever odd ball sees things other people do not, solving the crime in short order whilst failing to see the social mayhem he causes in the process.
Perhaps the closest series I can think to Chasing Shadows is Monk. The US detective with obsessive compulsive disorder or perhaps, to a lesser degree, Bones.
Chasing Shadows is well acted, utilizes engaging story lines but I do feel overplays the borderline autistic behaviour of its lead detective at times. Lead detective Sean runs around uprooting social norms to a degree that makes you come to wonder how he managed to get into the police force in the first place.
That said, Chasing Shadows is still a polished British crime drama that has me addicted, at least for the time being. A well deserved seven out of ten from me.
