I don't envy the editors of this collection. There are easier tasks than deciding what to choose from the 500+ stories Brad Bradbury has written in his 90+ years. These two volumes combine about 150 of them (stories, not years), so this is the biggest collection to date.

There are some classics in here that have been anthologized quite a few times: "There Will Come Soft Rains", "A Sound of Thunder", "Mars Is Heaven" among others.

From the lesser known stories I particularly enjoyed some of the creepy ones: e.g. "The Town Where No One Got Off", "Marionettes, Inc." and the wonderfully twisted "Night Call, Collect".

Some of the rocket-and-aliens-imagery may seem a little quaint today but I'd argue they only reinforce (if unintentionally) the nostalgia that has always pervaded the fiction of Ray Bradbury.

A rather amazing collection of stories from Bradbury, showcasing his imagination, his ability to shift tone and topics, and his fantastic use of language. (As a side note: I think I deserve a medal for accomplishing the Herculean task of getting through this nearly-1000 page tome ;-).

A writer as prolific and of such high quality as Ray Bradbury is that rarest of beings and this bumper collection of stories is a treat for readers everywhere. Bradbury's writing defies genre, rising above and beyond tropisms to ask fundamental questions of what it is to be human.

I didn't read the whole thing, but most of the short stories were worth reading. Bradbury's style is fairly simple, but every now and then he'll throw in a beautiful sentence.
He's obsessed with the futuristic planet Mars, and it's fun to join him on his eerie journies there.
