I hadn't heard or seen anything about this mini-series at all, I was browsing new shows and saw it pop up. When I realized Tom Hardy is the lead actor I tried it out and holy shit it's another epic show.
The visuals alone are worth checking out, acting is great so far and the storyline looks promising and mysterious. Definitely worth a look if you haven't already.
