Geonosis looks too much like Edgar Rice Burroughs’ Barsoom/Mars. Younger audiences wouldn’t catch the reference, but I did, and it took me out of the movie.

Maybe it reminded you of the Barsoom from your own imagination but for others probably not. It’s just another red planet. Vulcan being a red planet doesn’t take me out of the end of ST3. Of all the multitudinous things wrong with AOTC, this seems an odd one.

Personally, I found that Tatooine looked too much like Tunisia, which really took me out of Star Wars.
