How can you follow anything
The biggest problem I had with this movie was the lingo being used. It's all very dry and technical, and it's difficult to follow what's going on unless you have prior understanding to this kind of stuff. That and I found the sheer amount of arab names difficult to keep up with. I actually ended up turning on the subtitles so I could better understand the movie.
Not a huge fan of Katheryn Bigelow as a director, I find a lot of her movies quite boring.
