The Wizard of Oz

 First time watching it through in one go, previously have seen it all but a bit here, a bit there.  Really excellent foreshadowing in the (really quite lengthy) sepia piece upfront, everything in its expected place, (mis)remembered the Wizard reveal being much earlier than it actually was -- in fact the whole last part of the movie flew by: Wizard reveal, the resolution of the three helpers, the balloon, the red shoes, all of it done in an incredibly short period of time.

Although plot hole -- the Toto story doesn't get resolved, there's nothing to say Gulch isn't on her way back to grab that dog and get him put down, despite everything Dorothy went through...
