Quite forgettable.
Paladin comes, unasked for, to the rescue of a young sheriff who is the son and successor of an old friend and who wants to be different from his father by ruling by the book - five law books actually, those of the title.
The lesson offered here by Paladin, "forget about law books and written rules in a place like this, at least for many years, perhaps some day in a remote future..." might appear as common sense but one might consider it much less enlightened and progressive than what he usually fights for, even if in that case rules which Paladin and the people of the village see as unfit to their situation deal with nothing more terrible than drinking late in bars and spitting.
In any case, there are two serious flaws in this episode.
The young sheriff is too much of a fool, and not a nice one at that, for us to care much about improving his chances of survival and successful career. And, apart from an unremarkable gunfight, it is very wordy. The only relief comes from the character of the sheriff's mother, who treats him like he seems to deserve - a fairly stupid kid who still needs to grow up - but whose fault is it?
