Scott was a supporting character in most of TOS, and that character had a strange split-personality. Sometimes Scott was a calm, cool, pleasant professional who was obviously easy to get along with. ("The Galileo Seven", "The Corbomite Maneuver") Other times, Scott was a bit of a hot head, at times getting shrill. ("Who Mourns for Adonais?") Scott's third personality, which never made sense to me, was that of a drunk. "The Trouble with Tribbles" made sense, because everybody simply had too much to drink. But by TMP2, it seemed we were assuming that Scott regularly got into trouble. I never bought into that.
I always preferred his "Corbomite"/"Galileo" personality. He seemed to enjoy his work and had a disciplined personality. He was calm, cool and collected. And likable.

I totally agree. I am thinking specifically of how weak/odd he is in the Jack the Ripper and Memory Alpha episodes. The man can't handle the women. I'm disappointed in how (both eps) he comes across as either a victim, or a buffoon.
Isn't he also a little too bloodthirsty in Day of the Dove?
There is so much more to the man than his engines or his scotch.
