I can honestly say I haven't "felt" this way towards a TV show since Lost.
After it was obvious Lost was a huge cult hit, many shows tried to jump on the bandwagon. Invasion, The Nine, Flash Forward, The Event, just to name a few. While these shows weren't necessarily bad on their own, they just felt "hollow" compared to Lost. Like they were either lacking something, or trying too hard to emulate Lost.
Then along comes Once Upon A Time, and I think it hit the nail square on the head.
Like Lost, this show is at its heart a character drama more than anything else. Add in some phenomenal story telling, a dash of mystery, a pinch of action, and sprinkle with some fantasy/sci-fi..... and you have the recipe for another winner.
Thank you mister Horowitz. I just finally got over Lost, now I have to go through this crap again. ;)
