Yeah, some of these stories are undeniably dated and there are a few that are a bit on the silly side, but this has got too many classic stories to give it anything less than 5 stars: There's Matheson's classic first story, 'Born of Man and Woman', about a mutant child, intriguingly written in broken, invented English; 'Blood Son' about another mad child who wants to be a vampire; 'Witch War', about telekinesis and the use of little girls as weapons; 'Through Channels' an unusual, innovative horror story presaging the tech-horror trend of modern times; 'F-' a nominal sci-fi/time-travel tale with a very amusing central conceit which I won't reveal; 'Death Ship', the inspiration for the classic 'Twilight Zone' episode of the same name; 'The Disinheritors' a clever story about slipping from reality into something else, and so on. Beyond all those stories I have two particular favorites, 'Legion of Plotters' and 'The Last Day'. The former is, as Matheson described it, the ultimate in paranoia, as our protagonist slowly determines that all the minor annoyances that come upon him are part of a vast conspiracy against him. 'The Last Day' is probably my very favorite story in the collection, and truly depressing but also kind of touching story about, you guessed it, the end of the world.
Anyway, I could just keep going on and on with specifics as there are still quite a few great stories here that I haven't mentioned, (such as `Lover, When You're Near Me', `Mad House', `Little Girl Lost' etc.) but you get the idea. Very cool stuff, check it out. (The latter two Matheson collections are very good as well, though this one is probably my favorite of the 3. They're all worth getting, definitely)
