Query: A worthy purchase

Both are very much entertaining but you must stretch some credibility for one of these stories.If you can discount certain omissions and science screw-ups, then "Enemy Within" becomes a classic. Sorry, shuttlecrafts existed in season 1 so lack of any reference here is suspicious. And at that extrme temperature, no phaser is going to work let alone a human live."Mudd's Women" is the better of the two in terms of plot and concepts since it's possible that a temporarily age-reducing drug could be made whereas you can't circumvent physics and shuttles. Mudd is a wonderful character, devious to the extreme. This alone makes it worthwhile but there are plenty of good elements.
