2.5 stars ... and that's being generous. This collection of stories about Mars reminded me of Edgar Rice Burroughs stories. But where Burroughs entertained with adventures and action, Bradbury expounded on various themes, mostly anti-war and anti-establishment. The science in this fictional work played bit parts, merely a vehicle to get to a theatre of operations far removed from old Earth. A place where scenarios about preserving nature and archeological sites had paramount value. A place where minorities could start anew without the yoke of their oppressors dragging them through the dust. A place where the past could be preserved at the expense of Martian sanity. Rockets and atomic radio epitomized the Earth technological achievements. The Martians were vulnerable due to their telepathy and inward focus. Even less believable was the travel time to and from Earth -- unrealistically short considering the vast distances and plotting the different orbits of Earth and Mars to take advantage of launch windows. I skimmed many of these stories, I admit. I was either bored or frustrated. Some of them shine, like the tale about Spender and the one towards the end of the collection about the house running on autopilot. Otherwise, I'd sooner forget I read them.
