Season 1 was by far the best. 2 is a disaster. 3 is somewhat better than 2.
On another note, for a show that invokes the premise that "evil is made, not born", they sure as hell seem to go out of the way to portray nature over nurture by having children take on the characteristics and choices of their parents.
Emma is very much like Snow and Charming, in many ways, minus her issues with trust and such, and the show and publicity folks go out of their way to emphasize that with the pictures of how she holds her sword, etc.
Despite having been raised by Regina, Henry is much more like the Charming side of the family.
Despite having not been raised by Cora, one bad things turns what's her face/dead witch walking (I presume) into a mini-Cora.
Regina is much like Cora in how she reacts to being slighted, though obviously nurture could play a role there.
Neal ended up making the same mistakes his father did, abandoning his family and putting his wants/needs to get back to Emma/Henry over what was good for the rest of the realm.
I'm sure there are other examples, but it just strikes me that, as often is the case, what the show shows me is very different from what the creators tell me they are showing.
