I read a short synopsis about this episode before watching it, and I wasn't expecting too much from it, because the storyline wasn't sounding all that interesting, since I don't really like the Rumpelstiltskin character, but it turned out to be unexpectedly good! It was the tale of how Rumpelstiltskin started turning evil! And it was very interesting!
Meanwhile, in the present, there was a very good storyline as well, with the battle for the sherriff position! Very interesting stuff, and some interesting tactics used in the battle as well, by both sides of the battle.
Overall, a very good episode, and I can't wait for more! Keep it up, OUaT!
