Started watching Utopia last night; not the Amazon Prime series, but an ABC series that started in 2014 - it's the same team behind Frontline, if anyone remembers that, and is very much in the same vein as that or The Games (John Clarke's series about the Sydney Olympics.
Looks like it'll be the perfect follow-on after watching something full-on or brain-intensive prior to bedtime - we had been using Community for that, but we've found the recent episodes (towards the end of S3) have kinda jumped the shark.
And, although I know it's been mentioned prior, another plug for Breeders, created by and starring Martin Freeman et al: must-watch viewing for anyone with kids and probably a great recommendation for those you're trying to scare off having them! We've just finished season two, but I read they've signed up for a third season.
