Here’s the original:
1. Kids who have seen all of the movies, I-VI, do not identify with Han Solo nearly as much as they do with young Anakin. For them (and Lucas), Anakin is the main character who “becomes bad,” and then finds redemption at the end of VI. Starting from I, the movie is about Vader not Luke.
Which means that kids today are seeing a different theme. They see a story about a good person who grows up, becomes bad, and finds redemption; adults saw a movie about good guys vs. bad guys, that there are good guys and bad guys. Whatever the other relative merits of the movies, the full arc is more human and complete than IV-VI.
2. (Some) of the pictures are to scale, i.e. the relative heights do indeed parallel their relative importance. Why is R2D2 so big?
Lucas said that the movies are driven by the character R2D2; not that he is the most important, and not because he saves everyone at various points, but because he provides the impetus for everyone’s actions. This makes R2D2 the perfect Macguffin; inexplicable but desirable, pushing and pulling all the characters. He “is” the secret plans; he drags C3PO into a pod and across a desert; brings Ben and Luke together; etc, until ultimately getting shot in an X-Wing forcing Luke to finally give himself up to the Force.
Most stories have a Macguffin (or two) but you want to make sure your life doesn’t use them: something you pursue, or which motivates you, drives you, that, after all, turns out to be pretty meaningless. Sex, Lies, And Videotape’s (the last Soderbergh movie worth seeing twice) main Macguffin is Annie McDowell.
3. Most of the characters appeared in more than one movie, but only some (e.g. Anakin/Vader, Obi-Wan/Ben, Palpatine/The Emperor) appear more than once in the picture. Why? The obvious answer is that they were played by different actors. But taken literally, they are indeed different characters; there’s almost no overlap between Darth Vader and Anakin Skywalker or Obi-Wan and Ben.
Technically (as it applies to a story) that is a failing in character development; even radically changed characters need retain a commonality of identity, because that’s how it happens in real life: individuals may feel there’s a clear break from their past such that the current self is indistinguishable from the old self, but in most cases that simply isn’t true. “Wow,” they say at you 20 year reunion much to your amazement, “you haven’t changed at all.” And your immediate thought is, “well, they just don’t know me.”
4. The most important question is asked by the guy above: “I thought these guys were important?” He thought that because he was, in essence, told to think it. These are the main characters, he was told, reinforced by all of the extra marketing. One can imagine how angry a person might be to discover that the main character isn’t the main character; that, after all, they were merely two dimensional supporting cast in someone else’s movie.
