The stories feel like polished fables, not precisely realistic.

The plot complications occasionally feel forced, and Henry’s overwhelming dyspepsia sometimes comes off as meanspirited and a little mystifying (through two episodes, anyway). But Mr. Davies, as “Doctor Who” fans know, has perfected a style of propulsive, almost manic comic dialogue with an undercoating of melancholy, and there are plenty of hilarious and touching moments in Cucumber.

These episodes of Banana are lovely self-standing short stories that build to revelatory moments, but then they also add scope and layers of depth to “Cucumber.”
