I'm a claustrophobe artist who loves cave formations but dislikes going underground, so a documentary on a French cave filled with both beautiful calcite speleothems (fancy word of the day) and astonishing 30K+ year old artwork was a natural for me. It's a bit long, it's a little strange (hey, it's Werner Herzog) and it's repetitive, but I'd see it again.
Avatar gave me a monster migraine and I'm planning to watch Thor in 2D only, but this movie had a genuine reason for using a 3D camera; without that, it would be almost impossible to make out the complicated undulations in the cave walls and the way the paintings relate to them. It was worth the spacy feeling and eyestrain for the rest of the afternoon.
Not a date movie, not for action fans. Prepare to sit back and meditate on the depths of time and the human spirit. (Yeah, I giggled once or twice at Herzog's wilder leaps of metaphor...)
I liked Electro's design and it looks like there will be a bigger focus on humor (how good that humor is is another issue). But Spectacular Spider-Man was probably the best translation of Spidey in ages.
