I never heard these records before, but decided to dive in, frankly expecting them to be pretty stupid. I was very wrong to think that...they're quite fun, and it's intetesting that the overall characterizations are surprisingly on or near target. The writing definitely reflects a familiarity with the series.
There does seem to be a tendency with "adaptation" versions of McCoy where he becomes more cantankerous and snappish than he "really" would be, at least as often. You never seem to get the "why not try a carrot instead of a stick" McCoy, or the "Why not ask Jim Kirk? He's a pretty honest guy" McCoy. It's always the "dammit Jim I'm a doctor, not a blasted switchboard operator!" McCoy. I suppose the abbreviated nature of the stories don't lend themselves to that type of dialogue. A bit jarring at times, with original-era McCoy suddenly with a temperament you'd expect in maybe Encounter at Farpoint!
