Love Is Blind

Netflix, streaming now

​Season four of the OG series is upon us, and we all know the drill at this point — producers put a load of people trying to find love/fame, who are only too willing to say ‘I do’ to randomers in that quest, in front of the cameras. Singles who want to be loved for who they are (not because they’re HAWT, ’n’ stuff) have signed up for the less-conventional approach to modern dating. So, under the collective wing of Nick and Vanessa Lachey, hopefuls herd themselves to Seattle in the hopes of getting engaged without ever meeting. New episodes will roll out each Friday across 12 instalments, following each couple’s journey for love — as they move in together, plan their wedding, and find out if their physical connection matches the “strong emotional bond” initially developed in the pods. When their big day arrives, will real-world realities push them apart, or will they marry regardless?

I Am Georgina
