We are going to see it as well, I've been surprised at all of the reviews.
I just picked up the movie Russian Ark on DVD. If you want to see a cameraman almost have a complete mental and physical breakdown, this is the movie. It's a tour of the Hermitage, and how it has changed/looked over the past 300 years or so. It's interesting/beautiful, you follow this person around and as he goes in and out of rooms, the eras change.
I won't give away what makes it amazing (I may have already though).
