The OA (2016)

A young woman who was blind returns home after seven years missing, able to see, and gathers a group of teenagers to hear how it happened. Brit Marling and Zal Batmanglij build the idea of travelling between dimensions around a set of synchronised movements rather than any machine, which you will find either moving or silly. Netflix cancelled it after two seasons on a cliffhanger, so go in for the ride, not the answers.
