Like a lot of filmgoers, I'm growing weary of the use of 3D. It's occasionally spectacular, but more often just a distraction and a means to justify higher ticket prices.

Like a lot of filmgoers, I'm growing weary of the use of 3D. It's occasionally spectacular, but more often just a distraction and a means to justify higher ticket prices.

After seeing Werner Herzog's new documentary "Cave of Forgotten Dreams," I'm in love with the possibility again. The 3D film is simple, peaceful, almost meditative - and a wholly unique experience.

Herzog explores the Chauvet cave, an ancient time capsule in southern France.

The walls of the cave are lined with paintings - some dating back some 32,000 years - that are the oldest known to exist.

Endlessly and wonderfully eccentric director Herzog again gives us a glimpse into his unique perspective here.

Narrating in his unmistakable accent, Herzog reflects on our modern connection to these ancient paintings. Interviews with eager and passionate archeologists shed more light on the subject.

Speaking of shedding light, Herzog's limited lighting options in the cave actually work to his advantage. As he tracks light across the cave walls, it's practically hypnotic.

The use of 3D, it turns out, is essential. The contours of the cave walls are vital to appreciating the paintings.

Herzog ruminates on the nature of art and humanity at length. Action it is not, but it's this week's best bet.
