Just watched this as part of a rewatch of Tin Man and Alice, since they were all directed by the same guy who also wrote Alice and Neverland. Well I thought that it was very well done, and just as OM1 said, it had a bit of a Harry Potter feel to it. I would like to see this turned into a regular series, but I'm not getting my hopes up.
But after watching all three miniseries in rapid succession, I've been thinking about which one I like the most...
Now Tin Man had an excellent take on the Wizard of Oz story with a great cast to back it up, however I think it suffered from the fact that it was divided into three parts instead of two. IMO, the first part dragged A LOT. Without damaging the whole story, I think that it could've all been concentrated into two parts, but the fact that there were three parts is a big minus. Alice also dragged a bit in the beginning but it started to pick up towards the end of the first part, however Neverland on the other hand was great from the get-go. So it's Tin Man in third, Alice in second, and Neverland in first, but it's all very close.
