No pun intended - Diane Kruger whom I (and I assume many others) had discovered in the movie Troy, has been in quite a lot of movies. I assume she tries to get better scripted stuff than this most of the time. But one has to pay the bills too - also the script may have sounded better than what came out of it - including all the cliches we get served .... you almost know from the get go what is what.
The main male character seems weird - and he has quite the character flaws. Also he changes attitude ... and intellect it seems. So I get the 4 rating ... what saves it a little for me: Hank Azaria ... the guy has fun to say the least! I actually would love to see a spin off with him playing that character! There is a way more interesting movie there ... and him being here and there (character wise) ... well I can take and dig that to a degree. He has the charisma to carry that though ... also be aware, while this is rated R, there is no real nudity in this. If this is one of the reasons you watch.. well thrillers like this one. Still it gets steamy from time to time - just don't lose your mind over it ... although you won't really care in the end ... twists and all that.
