"This has a flaw," does NOT equal "This is a bad thing and I hate it and you are stupid for liking it."
"I like this," does NOT equal "I hate that and you are stupid for liking it."
"This is an evolved form," does NOT mean "that is ugly, stupid, and worthless, and so are you."
"That is the classic form," does NOT mean "this is watered down, mutated, and unnecessary, and you are ignorant for liking it."
All things evolve/advance -- airplane technology and game mechanics, strategic doctrines and game design philosophy.
Gary Gygax was the leader in evolving and advancing the D&D game, even from the first publication of Original D&D. He produced many supplements (pretty much immediately) for OD&D. He and others wrote expansions, advancements, and new rules (constantly) in The Dragon magazine.
Within 3 years of the first OD&D rules, TSR produced Basic D&D -- evolved from OD&D.
Within 4 years, Gygax, himself, produced Advanced D&D -- advanced from OD&D and BD&D.
And Gygax continued to advance and evolve the D&D game in the pages of The Dragon and Dragon magazines. He produced Unearthed Arcana which expanded the game even more.
Gygax has said that before he left TSR, he was contemplating another revision to the game (even including a skill system). Gygax has said that he never even played his campaigns straight out of the rule books. His personal table game was evolving/advancing faster than the published form. The master himself didn't consider the game perfect and sacrosanct as people now think of it.
And read Dragonsfoot sometime -- people are *still* discussing house rules and "fixes" for things in the AD&D rules. (The same kinds of discussions for house rules and fixes take place here on ENWorld for things in the D&D3 rules.)
With airplane technology, we can identify certain eras -- WWI, WWII, jet age, modern (for examples) -- but the advances didn't come in big jumps. The Spitfire didn't spring whole from the Camel. But advances in airplanes does not detract from the beauty and possibly even preference for previous planes. (Personally, I love WWII fighters the most of all the eras. I'm not an emotional fan of the jets and modern era planes -- but I recognize and appreciate the advances and evolution of the technology.)
We usually identify D&D editions as Original D&D, Basic (usually including Expert, Companion, Masters, and Immortal) D&D, Advanced D&D (1st edition), Advanced D&D Second Edition, and D&D 3rd edition (usually including the 3.5 revision). But each edition didn't just pop up wholly on its own -- it was a process of regular and constant advancement and evolution. This advancement and evolution is healthy and natural, and dare I say, necessary.
The OD&D game of 1977 was not the same as the OD&D game of 1974. The AD&D1 game of 1988 was not the same as the AD&D1 game of 1978. The AD&D2 game of 1999 was not the same as the AD&D2 game of 1989. Even before the successor editions were published, the game had changed -- advanced, evolved. Hell, the AD&D1 game played in my home (for almost 15 years) was not the same AD&D1 game played in your home. And it's all the same with D&D3.
But somehow, some people have this idea that D&D went from perfect beginning to perfect advancement and stayed there, in all it's perfect glory for a decade or two. And then gremlins started mucking with it and a new edition popped up from out of nowhere and without necessity. That's not what happened. The game is still advancing and evolving -- the game was never perfect, and it still isn't perfect.
When I was an airplane enthusiast (~6 years past, now), I never heard or read "era wars" or even "plane wars" among other enthusiasts. People could discuss the good and bad about all airplanes, from all eras, and no one felt offended or slighted. But then, also, no one intended offense or slight. Admitting that the jet engine is a better form of thrust is not, and would never be taken as, a slap in the face of the prop-lovers.
But here, among D&D enthusiasts, the lines of war are well marked. We can't discuss the good and bad about any edition without someone who prefers that edition taking offense or slight. And sometimes an offense or slight is intentional. And the take-offense and give-offense goes both ways. (I won't even give an example in this post because such would just provoke an edition war.)
Why are D&D enthusiasts so polar and quick to offend/take offense? It's almost pathological. Look at the responses to my analogy. How many people took comparing AD&D1 with WWII airplanes as an insult? (Should I take insult from that, because WWII airplanes are my favorites?) WWII was the era when airplanes really became a power in the world. Air superiority became a strategic necessity. The planes were constantly being upgraded and tweaked to for speed, manueverability, range, and altitude. It was an important and dynamic period in airplane technology. [sarcasm]But, of course, I meant the comparison strictly to insult AD&D1.[/sarcasm]
It has actually become no fun to discuss D&D here, because everything is taken as a spark for an edition war. There is no discussion for understanding, there is only fights.
For the record:
I do not hate AD&D. In fact, I love it.* If you find that statement hard to believe, then maybe you should reconsider how you discuss the game, and how you take how others discuss the game.

*In fact, what makes me love D&D3 is that it is so much like AD&D1. The new edition combines its roots and its evolution for something I like a lot.
