About 20-25 minutes per episode. Honestly, Season 1 is pretty decent, it does end on a cliffhanger but that's because when the project was announced it was always planned to have two seasons. So many people didn't realize this when it first appeared on Netflix. I haven't watched Season 2 but apparently, it's not that great.Meh 4 episodes for £20 is a bit steep unless they are long episodes. Can anyone who has seen it comment on episode length?
