Fleabag (2016)

Twelve episodes across two seasons, and each season ends on a moment a newcomer will not forget. The first closes on a turn that changes how you read every joke before it. Phoebe Waller-Bridge's heroine keeps glancing at the camera to let you in on things, which makes watching with someone feel like a three-way conspiracy, and season two finds a brilliant way to play with that habit. Be warned that it is frank about sex and grief, and that you can finish the whole thing in a weekend.
