Streaming service: Amazone Prime

Premiere date: First half of 2019

Why it's must-watch TV: Amazon's TV adaptation of Neil Gaiman and Terry Pratchett's 1990 satirical novel of the same name will be catnip for sci-fi and fantasy fans. David Tennant as a hot demon? Check. Michael Sheen as a sizzling angel with bleach blond hair? Check. I mean, what more could you want, people? Expect this unlikely buddy comedy and oddly profound religious allegory to blow your mind. The six-episode miniseries will focus on the imminent End of Days, and why an angel and a demon decide to spend the remainder of their time on Earth with mankind rather than see humanity destroyed. The unlikely friends end up keeping an eye on the Antichrist as he grows up, except there's a mishap and the boy they are monitoring is actually just a normal boy. Yeah, that means the real antichrist is somewhere out there, just living a regular life.
