I can't wait for this one. The trailer was awesome and the little clips I have seen look really good. Whether it should go longer than a season I'm not sure yet. They seem to have the season mapped out and that means the overall story should be stronger. Adding more and more means they'll just have to start making it up as they go along and that could make it weaker.
Agreed with that last statement, I think that's what hurt S2 for me. "We've made Regina the big bad, how do we now redeem her but still make her a bit evil... and make that last a whole season".
I'm excited to see another Lost alumni here (Naveen Andrews (Sayid in Lost) as Jafar) but I hope they treat him better than they did Jorge Garcia (Hurley in Lost) who plays Tiny... is that his name? The giant who Cora shrunk? Bleugh
The last said about his episode the better. Oh Jorge you're so much better than that
