The subject matter of this 1st season,a Hannibal Lecteresque serial killer inspiring a group of potential killers from his prison cell,is the core of the plot;its a simple idea borrowed from the Thomas Harris novel 'Red Dragon' and expanded into several hours of drama,action and killings(mainly by stabbings as noted by many reviewers).
Serial killer James Purefoy does escape,as Lecter did in the Harris novels,and conducts a campaign of revenge against the FBI agent who captured him,Kevin Bacon,and uses his followers as the means to bring him down.
I liked the performance of Purefoy having seen him excel in the excellent 'Rome' and in several poor action movies that didn't help his career.Here he has a meaty role and uses it to create a clever,manipulative 'teacher' who goads his followers to commit the crimes that start the manhunt by law enforcement agencies including the FBI of course.
Bacon becomes instrumental in the hunt for Purefoy and his cult, members of which start comming out of the woodwork;herin lies part of the success of this series:you don't know whom has come under the influence of Purefoy and will 'stab' the good guys in the back as the episodes unravel.
It makes for entertaining viewing if you put aside the stabbings.There has been a good build up of the characters on the FBI side and augers well for season 2 I hope.
