Query: Disappointing

I wanted very much to like this book, being a reader who typically enjoys time-travel stories, but such was not the case. I found it to be choppy, largely unstructured despite the built-in chronology, and peopled with unconvincing characters. Jeff was okay, but Pamela was (to me, at least) thoroughly uninteresting. The dialogue throughout the book was authorese rather than the way real people talk, and the quite intriguing first half deteriorated into a morass of repetitive and boring mini-travelogues. Far from being "in the tradition of Jack Finney," as the book jacket would have us believe, Replay was an amateurish mess. Don't waste your money and time.
