What makes the show good?. As mentioned here
"What makes "The Wonder Years" so appealing is that many can identify with what was happening in Kevin's life. Not only could those who lived through the 60's and 70's relate to the historical events, but almost anyone who was a teenager can relate to Kevin's personal adventures. . Most of us ..... experience all these other pivotal stages on our trip through puberty and adolescence into adulthood. These times really are wonder years, the time when we learn how the world and it's people work. "
Mayur says it even more lucidly here
"So many years after the show ended when I saw Kevin Arnold's pic in one of my friends computer screen NOSTALGIA did HURT. I mean it brought back memories of the yesteryears. It was very easy to relate to everything that Kevin was going through although I was from another world in India. His love interest the cute Winnie Cooper made it all the more interesting. Loved his best friend, though he did look like a nerd. I specially remembered a scene when Kevin kissed Winnie in the beach. Saying this might sound like saying a lot but it is just the truth. Sometimes the show seemed to me more important the books that I studied in school. A tutorial. It will always be close to my heart and fondly remembered. I can assume its like this for many of us around the world"
Ofcourse, I also feel that TWY rings the Nostalgia bell so beautifully is the fact that, most of us remember our childhood as a bunch of incidents. But TWY reminds us, that each incident was part of a growing up process. The wonderful voice over by Daniel Stern brings the sentiment to the fore, that each incident made us learn something, feel something, regret something and aloowed us to feel bad, good, sorry or proud of oneself, but all in all those were the years that improved the quality of life itself.
