Even if you didn't like the movie starring Ben Affleck, you should read this anyway.
This collection of Philip K Dick's short stories, of which "Paycheck" is the first, is some of his best work. He manages to pack more ideas, more innovation, and sometimes more twists and turns, into his short stories than most authors can manage in a full-length novel. Pretty much every single one of these short stories could be turned into a full-length sci-fi movie in its own right, the way that "Paycheck" was.
There are common themes throughout- most of these stories are set in a slightly (or very) dystopian future where man's dependence on machines has changed their very nature, and often where a war has pummelled the landscape. There's often a bizarre blend of everyday family life, and post-apocalyptic trauma. Most of the core ideas are nothing short of brilliant, and very radical and quite political at the time they were written, and the execution of them usually very good as well.
The inclusion of the controversial "The Pre-Persons" is also interesting- a very moving and openly pro-life story about a future in which it's been made legal to kill children up to 12 years after they're born if they're unwanted. Powerful stuff.
If you're a fan of good sci-fi, you should have this on your shelf.
