I was fairly unimpressed with Aeon Flux. I thought I might like it but it was just too derivative a story, in my opinion. I did like the design aspects of the film. I thought it had an interesting take on what future tech will look like.
On the other hand, I quite enjoyed Syriana. As I was walking out of the theatre, I overheard a group talking about how it had no plot, and I thought: "did you see the same movie I did?"
