Agreed.
The inspiration behind the Foundation series, setting out to shorten the Dark Ages after the Decline and Fall of the Roman Empire, is great.
However, if you try reading those short stories again today, you're quickly reminded that early in his career, Asimov was already great at world building, but terrible with characters and dialog.
Add in the mismatch between the cultural norms of the 1940's (when the early Foundation stories were written) and the cultural norms today, and a rewrite was always going to be required.
