I LOVE this season TO DEATH! However, I feel that since it didn't have magic in Storybrooke that it doesn't have as much potential as the others where we get to see how everyone with their memories back react to everything. Plus, while Regina is still amazing here, I feel like she's more fleshed out and show that she became evil for more than just because a little girl broke a promise, showing that there were other factors involved than that REALLY WEAK reason. Plus the other seasons have more character development, especially for Regina.

3B wasn't my favorite, despite my love for Zelena.

Season 3 part A was so boring. The Neverland stuff was a drag. I did love the additions of Tink and Ariel. Loved 3 part B though.

none :-p but the other two are my favorites so .... and well S4 is indeed my least favorite

I loved S1 & S2

Not that I don't like it, it's good.

3A was pretty boring. I agree with Fieryrubes that Neverland was a drag. That arc went on for way too long. I didn't care much for 3B either mostly because of Zelena. I loved that Ariel finally came to the show because she is my favorite DP.
