For a fan who has read the books and seen the movies countless times, going to an event like this might seem somewhat redundant. However, it quickly became apparent that this would be a fun, shared experience for fans with people dressed up and cheering and booing at characters and moments in the film. The orchestra played the score perfectly, so much so that you often wonder if they are actually playing or if you are hearing the recorded soundtrack. I did notice some subtle differences between the live performance and the original movie score: pacing, cues, etc. These differences didn't detract from the experience (to be honest most people probably wouldn't notice) but reminded me that I was actually hearing the score live. It would have been cool if the theater we were in had surround speakers for a more immersive experience rather than all of the speakers at the stage.
