That stuff doesn't bug me as much as reading up on the whole issue of movie goers supposedly being too freaking dumb to get the reveal that Dorothy could have crossed back and forth to Oz, and had it as a dream instead. Of course, it does work for a solitary stand alone film, and it gave way to a an overused spoof reference.
But the problem isn't so much that Wizard of Oz is best remembered as a movie rather than a book, it's that ALL adaptions have to live in the shadow of that film. Even ones based on continuations of said book. Which is a shame, since more Oz really should be seen in film.
Anyway, I also forgot to mention that I detest the term remake when it comes to using a book/novel/short story/etc as source material. Unless you're directly trying to remake the movie, it's technically called a retelling. There's a difference between Remake (filming something that was already filmed using the original film as its source), Reboot (telling a completely new story with older characters to reestablish a new continuity), and Retelling (basing a film off of the original source material literature, but interpreting it differently than the first film based on the same book). A Christmas Carol has been told many times, but each slightly different than the last. All retellings, not remakes.
On that subject, Saban wants to launch a series of Power Ranger films. While I guess you could call this a "remake" (hard to tell if it's a full blown reboot or it's just a remake of the original series), one article lists it as "A Power Rangers Live Action Remake." What's wrong with that statement is obvious, but they realize that there has never been an animated Power Rangers series... no matter how hard Disney tried.
