Emma and Regina are about to find out that the portal has opened for a last time only to bring out a frozen evil in Storybrook.

After the simply fantastic Season 3 finale, I had high hopes for Season 4; and I'm pleased to say that this premiere episode did not disappoint!

The characters from "Frozen" have indeed come to "Once Upon a Time" and they were cast perfectly! It's scary just how well Georgina Haig, Elizabeth Lail, and Scott Michael Foster faithfully portray the characters of Elsa, Anna, and Kristoff respectively.

But, fear not, the characters from "Frozen" may have indeed been brought into the "Once Upon a Time" mythos but they don't overshadow the other story lines and characters. Emma continues to struggle with the consequences of her actions in the Season 3 finale, Regina has a very interesting story arc set up for her, Rumple and Belle get some very heartwarming scenes, and the rest of the characters all get their own moments to shine (whether they be small or large).

Overall, this episode was fantastic and a great start for Season 4! I can't wait to see what happens next!
