Unfortunately, just like the movie itself, this commentary doesn't hold a candle to the one from Star Trek II. Meyer as a commentator is above average and manages to keep the whole thing pretty endurable, but it doesn't help that he starts off very pretentiously, trying to convince us that Cliff Eidelman's crappy music is in reality superior to all the other Star Trek music (?!), Jerry Goldsmith included, which he dismisses as imitations of Star Wars. On the rest of the track he repeats some of his remarks from Wrath of Kahn and tell some anecdoted from the production, but the listener can clearly see he's by no means as at ease or informative as he was in that reference commentary from the previous movie.
Martin Flynn, relegated to Meyer's sidekick, speaks quite a lot and also tell various anecdotes, but nothing particularly insightful either.
