Superb episode once again creates an eerie mood around the familiar legend of the Loch Ness monster of Scotland, reputed to have been sighted in the loch for centuries, but only with the recent advent of photography and cameras has any documented evidence been found, though of course skeptics find ways to doubt that as well! Eyewitness accounts are interesting, and use of pictures, music, and nautical sound effects is extremely effective. Will resonate in particular with those of Scottish descent, who grew up with this tale. Of note that, although broadcast twentieth, this seems to have been filmed first(Nimoy's intro is a giveaway), though why such a long delay in airing is unknown.
