I have no other ways to say, that there actually no reasons, because there are actually none, sorry.
Yes, the thread title is too provocative (don't know, if some one would take such a conversation seriously, so it probably should be so), earlier I have explained the criteria of credibility I use in detail (but it's actually hard to comprehend), in addition the explanations I use do not contain all the chains necessary to connect facts, so the conversations actually help me to understand what people are miss in my explanations (and what is missing in my picture) and to show a way how to use the criteria of credibility (people don't understand what I actually do, and think that I don't consider their facts or don't believe that their arguments actually affect nothing, although I unconsciously may also abandon some facts, I don't deny, this).
To clarify the methodology (you may consider this as blah-blah-blah and don't take it seriously, believe it or not, but this explains why I believe that NGE is not just a mess and why people generally don't believe why it may be not just a mess):
- My reconstruction covers the base layer of the plot (the complementation conspiracy), which connects other layers.
- This layer contains statements (some are connected with facts, some are not), scattered facts (for example, the fusion of DNA of the test subject and Adam), some facts could be obtained only through connections (for example, the origin of Ayanami), some facts could be obtained only through visual hints (for example pillars of salt and inscriptions in Ayanami's room). Connections between the most of the pivot facts are intentionally removed to entrap a viewer.
- To solve the plot means to find the missing casual connections (you already have them in the most of other shows). The interpretation of the other layers may be purely speculative, because you operate only with motivations, but here you could find more or less solid solution, because you operate with facts.
- Chains of connections may branch (for example because you has incorrectly interpreted a fact obtained through connections), and you may get different solutions if you have not enough facts in your picture. The amount of facts you have determines the clarity of your solution, because you may get contradictions in some root points if you have enough facts to get connections between them. You may consider your solution as credible if you have not enough facts, because you may not notice the contradictions.
- There is only one credible plot exists (it's not possible to state this absolutely strictly, because it's hard to comprehend all the facts, but there are several root points such as a statement about the third impact from angels, Kaworu's deceive, behavior of the military in EoE which will obligatory give contradictions, and there are no other easy ways to connect facts in such a way which does not raise contradictions there).
- You may do not notice contradictions at all or introduce purely speculative entities which will hide the contradictions, so a credible plot should contain a minimum of such entities (the simpler solution should be preferred to more complex) and it's necessary to pay extra attention to this entities.
- There are no ways to easily connect facts by not using some of them (for example, from the Judaist mythology) literally, which indicates that they was intentionally used in such a way.
- It's absolutely not possible to solve this layer without EoE, but the end of the series clears some facts at this layer, so both are valuable.
- My explanations of the show should not be considered as absolutely credible, because I may misinterpret some facts and I definitely still have missing connections, but facts and connections from there may be useful, although personally I consider the solution enough credible to consider it as a the simplest possible underlying plot.
I have no intentions to converse on this, so just believe or not.
