I’m going to try to keep this only mildly spoiler-y, but considering people nowadays call “Spoiler!” over things that are in trailers (newsflash: that’s what trailers are, they tease you with spoilers so you’ll watch) I’m going to say; there may or may not be spoilers ahead.
I absolutely love Once Upon a Time. I remember when I first tried to watch the premiere in 2011, I thought it was really gimmicky and decided not to continue watching the series. Thanks to the amazing advent of Netflix bingeing, though, when Once Upon a Time was put on Netflix I sat and watched the first episode again. On second viewing of the premiere, more than the tale of Snow White and Prince Charming, I got sucked into the story of Emma and Henry.
