The Second Coming (UK)
The Second Coming is a two-part series created and written by Russell T. Davies (Doctor Who, Years and Years), and stars Christopher Eccleston as a regular guy who gets lost on the moors outside of Manchester for 40 days. When he comes back to civilization he claims to be the son of god who has returned to bring a message to humanity.
This is touching and charming and small in a way that American television isn't. It grapples with larger issues by intimately connecting with characters living through them in their day-to-day lives. No spoilers, here. But this is a hearty recommendation to watch.
