Every year some new TV shows come out that seem based on very similar ideas. This year I noticed that Ringer and The Lying Game have rather similar concepts. Separated identical twins (played by the same actress), one rich one poor, swap places. One disappears and the poor sister attempts to find out what’s going on while impersonating the rich sister. More or less.
Grimm and Once Upon A Time both bring fairy tales into the real world but in rather different ways.
