Title: Perhaps a bit too wordy. Review: This is a fascinating topic and the authors did a good job of explaining their thesis. For the lay reader, however, some parts may be a bit technical and explained in too much detail. I almost think this could have been better presented to the non-scientist reader as a long magazine article rather than a full book.However, that is minor criticism; there were many intriguing ideas presented in this book. And I should really give it 5 stars -- the extra star awarded to the authors for debunking the ideas of that pompous populist, Carl Sagan (I can just hear him saying..."Only one civilization in the galaxy? NO! Billions and billions and billions..."). Does this product review convey a negative or positive sentiment?
Positive

Title: Quickly developed psoriasis Review: It makes coffee reasonably well, which is the main reason for its existence after all. But very soon after we bought it, it began developing a nasty-looking flaking and blistering on the face of the heating element. Doesn't affect its functionality but looks like hell.
