Arc rankings:
S2A – The most fun arc for me. Loved Snow/Emma in the EF, loved the new characters (Hook, Milah, Cora, Mulan, Aurora), had a nice pace and blend of magic/reality.
S1 – Original, captivating and contained many great episodes. But it did drag a bit, especially with the whole MM/David/Kathryn triangle. The framing of MM for murder was also very obvious.
S2B – Contained some good episodes but fell away after 2A. It felt like they didn’t quite know what direction to go in after Cora died.
S3A – Well planned arc, interesting story and captivating villain in Pan. I missed Storybrooke and the perpetual darkness got to me, but I did enjoy this arc.
S4A – Solid. No character development and plot inconsistencies were starting to get worse, but not bad either.
S3B – Just didn’t interest me that much. I couldn’t get into Zelena and the Oz flashbacks.
S4B – Boring. The queens of darkness didn’t interest me and the author storyline got messy.
S5A/S5B – Boring, annoying at times with hardly any episodes I’d rate as ‘good’. The plot was hopelessly inconsistent, the characters were butchered and the messages coming out of S5 were mixed and at times, outright distasteful.
