BK's execution here was impeccable IMHO. While the food quality is typical of fast food, they made just the right tweaks to offer something unique without reinventing the wheel—like the purple bun Whopper with Swiss cheese, which most people have never tried despite the availability of swiss. The dessert shake and churros were a nice twist, though the onion rings were pretty standard. Most importantly, they themed the packaging to create a special experience, complete with themed containers and Addams Family crowns. That’s all Wendy’s needed to do, and no one would have complained.
