Absolutely hated it I watched this movie on recommendation and really wish I hadn't for two main reasons. Firstly, the politics was way to strong. I could have put up with that, however, if it weren't for the second point which is that I had no sympathy whatsoever for the characters.
Lawrence, with his government job, should have known better than to bring a complete stranger on such an important trip without checking out her background first. But mostly it was Gina who didn't just not do anything for me, she actually made me really angry. We are led to believe she actually has feelings for Lawrence, but nothing she says or does backs that up. She's like Jekel and Hyde, apologizing one minute for an outburst then doing it again the next. At one point she reminds Lawrence that he sat down next to her, not the other way around, but I wanted to remind her that no-one forced her to behave the way she did. And her behaviour really was shameful. I spent the entire movie waiting for her comeuppance - which never came.
I gave this 4 stars only because I have seen worse.
