I think you can only take him so far from step one, then bring him back again, before it gets tedious. There were some fascinating storylines in the 70s showing some neat facets of the character, but if you read the next month or a few months after, chances are high that it wouldn't really matter whether or not you read the preceding stories. For all the heads the original Man of Steel mini series turned I think it was great for them to make an explosive break out of an admittedly great mold.
Hey, an even 8,000! Nice.
The ability to relate seems like a squirmy thing to me, because it doesn't have to be one or the other. I'm a lifelong comics and videogame guy but I still placed in two sports for Regions in high school. Most people find the Reeve act as Clark charming, but hopefully we can all agree that being a worm in front of his wife and son would be mortifying. In "Who Took the Super out of Superman?" he sets Edge straight and knocks Lombard senseless because he lets Clark be a real person. That to me is basically the same.
If this was solely for Superman's character and not general directions for other characters or parts of the franchise, I'd agree with never having rebooted.
