[Just in case someone is afraid of of spoilers]
When Regina, hamming it up and chewing all the scenery, said "I want to watch you bleed", I spontaneously giggled like Rumple, including the hand gesture.
God, I love when she's so spicy. And those dresses...
It's fun to see something other than lukewarm sugary cheesiness and perfection of Charmings. And I'm relieved we're finally saying goodbye to Frozen (or are we? dun dun dun). Too bad they resolved it all with a last minute ass-pull.
PS. I wonder how/if the inevitable Frozen 2: Freeze Colder will incorporate all that happened on Once.
