As I understand Burton's films yet, I personnally think that Burton is a real plastic artist and that he choose the movies he do in fonction of the visual aspect of it... "Ed Wood" is quite unique in Burton filmo and I don't really want to see "metaphysical" side on it; it destroy my pleasure to see it...
I think that sometime, too many peoples try to see "the movie behind" each movies and waste the pleasure of seeing movies. Of course, when you watch a movie by Antonioni or Bergman, you can play that question game... But when I watch a movie by peoples like Burton, or even Orson, I just sit and enjoy the movie for what I see "on screen"...
That remind me a funny scene in a documentary about Woody Allen I saw on TV where a critic explain to Woody what he saw in the movie "The purple rose of Cairo"... Woody finally got really mad and told him "Please, stop... I wrote and direct that movie, don't explain it to me!!!"...
Just my little opinion with my bad English
