I liked both movies too. I love the way they were shot, actually. Very kinetic and interesting angles.
I hated the way the second was shot. The camera moved around so fucking much that it made 3/4ths of the audience in the theater sick. You couldn't even tell what was going on because the camera never stopped shaking for the last 40 minutes of the movie.
There were two different directors for each movie. That's why the second one was a little different, especially with the movement in the second one. Can't remember the dudes name, but if you watch any of his other films, like bloody sunday about the clashes in the UK between irish and the uk army, they are shot in similar styles.
He was doing something else if I remember correctly so he couldn't do the second one. It's not that they didn't want the same guy, it was that their schedules didn't work.
