The movie may be strange, but having a spoiler in the title isn't that big a thing. I mean, I sat through both parts of Kill Bill and still enjoyed the ending.
As far as Return to Oz. Yeah, it's strange, and that's magnified for most people because it's darker than the Oz story they're used to. It's strange compared to the classic movie and the first book, and that's the popular view. If they kept reading the series, then they'd get into strange.
