“Do you want to make balloon faces?” Adam Driver continues to astonish as uncouth artist Adam, whose leg is in a cast after being hit by a truck. Hannah is tending to him, but she also has a new (Republican) boyfriend. It remains, effectively, the Lena Dunham Show (and she still finds it hard keeping her clothes on) but her best friend, Marnie (Allison Williams), is stealthily stealing the viewer's attention. Funny, poignant and dangerous TV. With Jemima Kirke.
