Smell this, I think it's expired...

One thing that I've noticed from the first film that's not in the second two was the sense of urgency. For the entire first half of the movie Frodo is being closely pursued by the Ringwraiths. Even when they are defeated, its 'let's get headed for Mordor'. Next they were trapped in Moria and then were being pursued by the Uruks down the Anduin. The whole movie had that feeling of hurry-or-you'll-get-caught that kept us all on the edge of our seats.

The Two Towers did not have this at all. I remember actually looking at my watch wondering why it seemed so long. I don't mean it was boring, I just wasn't into it as much. RotK was a little better, but still didn't have that same urgency that was in the Fellowship.
