Under the Skin the movie based on the book by Michel Faber. 

Meant to read this for a few months now. The premise looks interesting enough. 

Human sometimes has to step outside of themselves to see their own nature.

How we as "predatory" as we are evolved to be, or are we much more feeling than we like.

Unlike other human, to feel is not that easy for this alien. The premise that emotion in the form we understand would be foreign to an alien with a totally different evolution history.

I'm not even sure if alien would look like us. Richard Dawkins already reminded us there would be no elephant on other planet even if they have life, as our evolution history is unique to this planet.

Looking forward to reading this book and watching this movie, which ever comes first.
