Note: All of these ratings are on a 1-10 scale.
Quality of Writing: 6
Nothing spectacular here; fine word choice and sentence construction, but nothing to get excited about. The quotes were used well and did not feel forced as quotes sometimes can. Perhaps there were too many quotes for my usual tastes, but as I'm doing research on this topic, I found it helpful.
Pace: 3
Good point: this book is a fairly fast read. Bad points: all of the breaks in time, jumping around, etc. Usually it was explained and not horrifically confusing, but it is confusing for the first few paragraphs of each chapter, or each of the multiple breaks within that chapter.
Characters: 7
A fair amount of the characters described got their own chapter, in which I felt I got to know each of them well - especially true for the panoramic view of Baron de Coubertin, Connolly, and Sloane. However, if a character's chapter happened to be near the end of the book, I felt lacking until I read it, and some characters only got a paragraph. So no higher than a 7, I felt.
Enjoyability: 9
Without precedent, these games ran into more than their share of mismatches, miscommunications, and mishaps, which I enjoyed every minute of. It was also nice to revel in the glory of a legacy which I can still appreciate.
Insightfulness: 10
Who knew the first modern Olympians were such a ragtag bunch with a dream? I didn't. I knew absolutely nothing about the 1896 games - now I feel like an expert.
Ease of Reading: 8
Despite the time jumps, this is a fairly easy read. It explains anything that might be foreign to a non-sportsman like myself - such as the history of pole vaulting, or why the ground ought to be marked for the triple jump. I never found myself confused or frustrated.
Photos: 3
Sometimes, in the text, Reisler would describe a photograph in detail. So I would go look for it in the photo section, only to find, to my dismay, that it was not there. I would be quite disappointed. Also, the photos there were not what I was looking for in my research, so I found them unhelpful. Though I have no doubt they are probably the best extant pictures of an event that took place over 100 years ago.
All of this averages to a 6.5/10, which is a 3.3/5, hence the 3-star rating.
