^Absolutely. Saying people had no trouble with the original stardates is ridiculous. As you say, the makers of TOS got so many letters complaining about the stardates being out of order that Roddenberry had to concoct a handwave explanation in The Making of Star Trek (or maybe it was concocted for some other forum and repeated in TMoST) about how stardates are dependent on position and you get different values as you move through space.
And I don't see how replacing a stardate system that was intended from the start to be sheer gibberish with one that contains actual date information constitutes "dumbing down." The original point of stardates was to obscure the time frame of the series, since Roddenberry and Solow were aware that science fiction often tends to be too optimistic or too conservative about how long various advances will take, so that it would be safer to keep the actual timeframe fairly vague. Gradually, though, the series settled more and more on a specific timeframe, with references to 200 years or so accumulating in the series (with some exceptions), TMP and TWOK locking it down as the 23rd century, and finally TNG giving us definitive calendar dates. By now, the chronology of TOS is so well-defined that using a system deliberately designed to contain no chronological information of any kind seems pointless.
True, the movie's stardate system seems odd to those of us accustomed to the old system, but someone who looks at the new and different and sees it as automatically a bad thing has missed the entire philosophical point of Star Trek. It's an efficient way of conveying meaningful date information to the new audience while still acknowledging the forms of the original. Yes, it's a retcon, but replacing gibberish with coherence isn't really a significant retcon, because it's not like anything of any substance was eliminated.
