If you're a fan of Andrew Lincoln (Rick in The Walking Dead), you might also like to check out Afterlife, a psychological and supernatural British TV drama in which he plays a leading role. The series is superbly acted, but despite its critical and popular acclaim, it was unfortunately not renewed past its second season.
Aterlife is the story of a university professor, Dr. Robert Bridge (played by Lincoln), who has lost his young son. His son's death has led to his divorce and torn a seemingly irreparable hole in his life. Bridge is a skeptic who views psychics as unscrupulous fakes that give false hope to the living while draining their financial resources. Then he comes up against what appears to be the genuine article--Alison Mundy, brilliantly played by Lesley Sharp--who would like nothing more than to be freed from her ability to see and communicate with the spirits of the dead, including Bridge's son.
Of course, the first thing you need to adjust to in watching Afterlife is Andrew Lincoln's native British accent, which one tends to forget because of how well he performs his American drawl in The Walking Dead.
Afterlife is available through Amazon.
