Cute! Very cute! And satisfactory! Also I still don't know why there's a Season Seven of this show, but whatever. Let's take a look.
Cons:
The evil stepmother is silly in how evil she is. Clearly she and Mr. Gold have some sort of deal worked out, and I'm sure we'll learn more about that later... but come on. She wants Henry framed for theft to remove him from her life, she wants to prevent Jacinda from seeing Lucy for no good reason... it's just so campy. I know that we'll get more on her motivations at a later date, but at this point I'm kind of rolling my eyes.
The flashback story explains a lot about why we have some characters trapped in Hyperion Heights, but not others. But one problem it does have is its pacing... I feel like a ton of things happened very quickly, because we had to establish the origin story of Wish!Hook, the reason why Regina, Wish!Hook, and Henry are all together in the same place, why Emma isn't around, etc. etc. all in a very short period of time. We have the older, potbellied Hook being magicked into a young hot version conveniently, we have Wish!Hook doing a 180 on his apparent motivations, we have Emma showing up basically just to hug Henry, and then turning around and leaving again... all of this felt a bit unbalanced and almost like I wanted to see a two-parter. Is this because I want more Hook and Emma? Maybe. But I also think the story genuinely could have been balanced out a bit more.
