I'm not being hyperbolic when I say that ABC's 'Once Upon a Time' is unlike anything you've seen on television before. Its closest relative is probably a little-watched NBC miniseries called 'The 10th Kingdom' which aired in 2000, at least in the way it blends classic fairytales with the modern world to offer a whole new interpretation of pop culture's most familiar yarns.
'Once' also shares a certain amount of DNA with 'Lost,' since it was created by Edward Kitsis and Adam Horowitz, who wrote for the mystery series for the duration of its run (you can read Mo Ryan's recent interview with the duo here). But in its ideas, execution, and undeniable sense of whimsy, 'Once' is a unique creature, accessible to viewers from ages eight to 80.
Earlier this month, AOL TV visited the Vancouver set of the fantasy drama, wandering through the enchanting streets of fictional Storybrooke and talking with the cast about how the show is evolving so far. Join us after the jump for a hint of what you can expect when the show premieres on Sunday (8PM ET, ABC), and come back next week for a deeper look. Mild spoilers ahead.
