Nihal Arthanayake, Hayley Campbell and guest critic Lauren O’Neill review the biggest new TV and streaming shows. This week the team checks out Deadwater Fell on Channel 4, a David Tennant-starring thriller with a faint whiff of Broadchurch about it. Plus they ask whether Sky One’s political drama Cobra is the UK’s answer to Designated Survivor and check out the second season of Netflix’s hit comedy Sex Education. If that’s not enough, they also take a look at the first ever Winter Love Island and they’re joined by Justin Hawkins, the latest celebrity to have their secret identity revealed on ITV’s The Masked Singer.
