Neverland was a bizarre story arc. It seemed to focus more on unimpressive character development (more flip flopping) of the main characters and for the most part, ignoring a great deal of key Neverland characters. Even Rumplestiltskin's story lines, which are usually reasonable, were not all that great.
We got Tinkerbell, who felt like an extra. Tinkerbell didn't exactly add much to the Neverland experience.
Peter Pan was played wondefully by the actor. I can't say I am fan of this version of the character. I have no problems with him being evil, it is just the story line and how it is connected to Neverland felt weak. Rumplestiltskin's connection felt a little forced. I struggled a bit to identify a selfish man becoming a far more evil child with power beyond comprehension. Perhaps I was little disappointed that Peter Pan's character wasn't something more tragic based - like an unfortunate child who strayed.
Neal/Baelfire - Well that was disappointing... I'm sure he wasn't quite the key character people were hoping for in Neverland.
Hook - Fanservice for the ladies. A once potentially great character, who continues to lag. Back story didn't quite hit the spot for me.
Wendy and the Darling brothers - What was all that about? They just seem to exist, for the sake of existing.
The greatest "crime" seems to be around the Lost Boys. Felix is an unlikeable character, who we don't really learn anything about. There could have been some amazing character development for Emma and early on in the season, you might suspect that may be where the story is leading. There could have even been decent character development for Henry, with his notable absence of any childhood friends. By the way, what did happen to the lost boys after arriving in Storeybrooke? I guess we will never find out.
I can't wait to hear what the compelling reason for Storeybrooke coming back is.
