It's like somebody has taken every Covid conspiracy theory and made a TV series of it. Without spoiling the plot, there's a pandemic, mad scientists, vaccines with dubious properties and governments being controlled by a shadowy elite. Of course, this was written long before the pandemic but watching it now is particularly pertinent. There are holes in the plot and it does stretch credibility but it certainly keeps you enthralled. It's visually striking and it does have that very British slightly arty underground Channel 4 feel. We had just finished watching Misfits, another Channel 4 series so it was good to see that 'Curtis' again. I can't comment on the US version.
