Bad move for ABC's Once Upon a Time?

Alright, I don't know how many people on here watch this but I enjoy it immensely. Last night's season finale was awesome, especially the whole time travel scenario. It kind of gave a Back to the Future feel to it.
I had one major gripe though. Out of all the characters to choose from in the ENTIRE Disney universe to cross over into the world of Storybrooke ,they choose Frozen's Elsa?? Give me a break.
Just because the movie made tons of money and was a hit with children does not mean they should use it to get ratings. The show is great already. The show always ended with an amazing cliffhanger but this time, I was disappointed. No show deserves to waste its good fortunes over desperate needs for ratings.

Guess nobody watches this show on here but me lol.

Ok, well now I know where to go to talk to people about this show... Someplace else. lol

I love the show "Once Upon A Time", but I just found this forum yesterday.

I know that a lot of people seemed to be upset that they chose Elsa from "Frozen", but I think the writers of OUAT have proven themselves, and I have complete confidence that next season will be just as great as the previous seasons.
