The theme of the world travelling was discovering who he really is for himself and not because someone told him who he was supposed to be. Fighting fate in a sense.
Thinking it over, this approach to Decade also would've made it a better celebration of Heisei. People make much of how disparate the modern Rider shows are, but I think all of them engage with the self-determination theme we're talking about at one point or another.
Decade could've served as a grand summation for that in a lot of ways, while also connecting Heisei to what Showa was about. After all, the way Heisei explores self-determination is very different from the Showa style, but ultimately Rider-1's rebellion against Shocker is an act of self-determination.
Eesh, what a wasted opportunity. It bugs me the more I think about it.
Only if you ignore the large amount of exposition given in the first episode in favor of your own speculation.
No, I'm just ignoring the interpretation of it you favor as "obvious," because I don't think it's obvious at all. I think Yonemura tries to force that particular interpretation with stuff in his half of the show, to get the story where he wants it to go. I do not think the material itself makes the same interpretation in any way inevitable or necessary.
I have a broader issue with you here, though. The thing with stories is that you can't
actually tell someone they're interpreting it wrong unless you subscribe to the theory of authorial intent. Even if you did, Decade's a poor candidate for that since, in all, five different writers created the scripts. For instance, I don't think your ideas of Decade are wrong, but I also think they are no more valid than anyone else's.
As it happens, I don't subscribe to the theory of authorial intent at all. I reject it whole-heartedly in favor of the primacy of the individual's interpretation, for a number of reasons that aren't really worth going into here. If you don't like that, then you probably don't want to discuss writing with me. I'm more interested in discussing a range of opinions developed by audience members based on their own experience than the story's One True Meaning.
The narrator ending every episode saying "Destroy everything, correct everything!"
Yes, because the best way to analyze a long-form television series is to look for guidance from its end-of-episode catchphrase. Obviously, the true meaning of Evangelion was encapsulated by "And next time, there'll be more fanservice!"
The writers of my country(Brazil), in the later half of the 19th Century, spent years mostly writing about Meta-Text, arguing that the text should live by itself.
You actually damn Decade with faint praise just by making this comparison. Consider that you're going back to the 19th century to defend the writing style of a story... written in the
21st century. I would suggest that it's unacceptable to write a 21st century story at the same general level of sophistication as material written
two centuries prior.
