Check out "The Best of Trek". Some fans hated every single change in ST:TMP, too, and many of those were Roddenberry's doing. They wrote extensively about all of their peeves throughout 1980.
Further back, they were also peeved by TAS.
Wrath of Khan, too! Don't forget "Indiana Skywalker Meets the Son of Star Trek" in Best of Trek #7:
Wrath of Khan, on the other hand, is a shoot-'em-up in the style of Star Wars and Raiders of the Lost Ark - very thrilling the first time you see it, but not much left for a second viewing...
...by the time of Wrath of Khan, the Federation appears to have been overwhelmed and drastically altered by some cataclysm - possibly revolution...
...the Enterprise has become, for all intents and purposes, a battleship...
...a wife and child, of course, who are promptly produced (out of thin air), providing [Kirk] with new (and boring) preoccupations...
...For the first time, Nimoy has been miscast as Spock...
...the Star Trek figures, as scripted, are unrecognizable...
...the conclusion is inevitable; No respect for the characters as characters was operating here. If, in the overall interests of a flashy production, the heroes had to be undignified, so be it.
We're stuck in a time loop, people!
