Get the right edition! - By: Peter Robinson, 09 Sep 2008 
Darwin's book is seminal in the understanding of emotions, & is just as relevant today as it was when it was first published in 1872.
However, you must be careful to buy the right edition. In particular, Amazon is rather cavalier about sharing reviews & "search inside" images between different editions that just happen to have the same title. Don't let this mislead you.
Paul Ekman's definitive third edition published by Fontana [ISBN 0006387349] starts with the text & illustrations (including photographs) from the 1889 second edition, & includes further changes that Charles Darwin had indicated but which his son Francis did not include. Ekman adds further photographs & his own comments, which put the work fully into a modern context. It's a fine piece of scholarship.
On the other hand, the Filiquarian edition [ISBN 1599869152] is complete rubbish. It just reprints the freely available text of the second edition with no illustrations & no copy editing. Avoid it.
The Ekman edition fully deserves a 5* review, but I am only giving four because Amazon will attach this review to alll the editions, & I want you to read it & realise the difference!
