I think Malkovich captures more accurately the character created by Patricia Highsmith than Damon does. In "Ripley's Game" we see a more perverse and tactician criminal, very near of what Highsmith describes in her novels.
I also am grateful to see this film brought to the end of the 20th Century, plenty of mobile phones, terrific Alfa Romeo cars and modern costume design. The story per se doesn't have significant changes and the film is perfectly set out in another time. In "Talented Mr. Ripley" the story goes back to the 50's or 60's, that is, the time Ms. Highsmith wrote the Ripley's series.
The rest of characters are really interesting. Dougray Scott has an ascending role and not only has he got more presence in the film as it goes on, but this presence is more convincing little by little. Good job.
Another good thing is that you don't have to see the first part to enjoy completely this "Ripley's Game". Very recommendable.
