The only official film sequel to The Wizard of Oz is an animated film. There have been quite a few remakes and different takes on the story, but nothing that touches on the direct continuity of Star Wars.

All in all, it is my opinion. I'm not trying to convince anyone, and I'm not going to be convinced. Personally, I also feel that the novelization of ANH should be updated to reflect the other novelizations (ie removing the concept that the emperor was just a figurehead).

I love these films just like anyone else here, and really love being able to discuss them with everyone on the site. I actually just released on fe.org what I believe is the shortest narratively-sound version of TPM ever created, if that helps clear up some of my own views on the PT and Star Wars in general.

And to be perfectly honest, I would be just as happy watching PT edits with film grain added and colors washed out, with cgi scaled back. I just want to be able to watch the films in episodic order without a huge difference in visuals. I simply wish that the line was a little more blurred between the PT and the OT.
