This is a tricky one: Repent, Harlequin!, Said the Ticktockman by Harlan Ellison is a metaphor against an over-reglemented world. It’s old, and I’m afraid to my eyes it hasn’t aged too well. It’s got an important message, and the scenario isn’t bad either, and the language is poetic, but it didn’t capture me at all.
On the other hand, even months or years later I can remember the feeling, the vibe, the discomfort of the world described, so I think my initial review was too harsh.
