Pros
Pretty much all of the Frozen stuff. Everyone was well cast, and their story is actually pretty engaging.
The Rumbelle ballroom dance
Rumple’s speech to Neal. Yeah I know it was tainted because of the whole “I killed Zelena out of vengeance and lied to Belle about it” issue, but otherwise I felt the rest of his speech was actually well written and fitting for the character.
The reveal of the iconic Sorcerer Hat. Looked very cool.
Seeing Sidney again.
Marshmallow was fun to see.
Hints that we’ll finally be learning who wrote the book soon.
Cons
Regina backsliding her character development by wanting to get rid of Marian. Yeah she saved her from Marshmallow, but she was still plotting to kill her only minutes earlier and still wants her out of the picture.
