I gave this book as a gift, then read it and regretted. The commentary was knowledgeable but the stories tended to be very pulp-y and, to me, only interesting for historic or nostalgic value. Most readers' tastes will have evolved past most of these tales. The worst aren't really even stories, in the sense of plot or characters, but have the quality of bad Twilight Zone episodes based entirely on a single "Wouldn't it be weird" punchline.Sorry to be negative, but I was genuinely disappointed with at least half of the collection. Even the stories listed as good examples in the editorial review are mostly trivial and now cliche. For escapist time travel yarns, you might try Heinlein's "The Door Into Summer", Willis's "Doomsday Book" or "To Say Nothing Of The Dog", or (what the heck) Twain's "A Connecticut Yankee in King Arthur's Court".
