It drags on too long...

But it was an interesting drama in its own way. Quite a fresh idea with switching personalities and good acting of the main character allowed me to watch the series to the end.
The first episodes were definitely more interesting, unfortunately the further they go, the more predictable the solutions. Betrayal, lies, the desire for power, madness, separated lovers reunite, good triumphs over evil... and they lived happily ever after... I have watched better and much worse dramas.
