7. Murky Cinematography
It's well known that 3D functions best with the bright, spritely colours of animated films, while cinematographers tend to avoid using darker shades, especially in live action films, because 3D glasses can darken the image up to 30%. If a scene is going to be dark, then the colour grading will need to be adjusted to compensate for 3D screenings, though going by last night's 3D showing of World War Z, post-production has not factored this in. Early on, when Gerry and his family are fleeing from a gang of zombies around a dim complex, the lack of light combined with the poor editing makes it close to impossible to work out exactly what's going on; we can see people running, zombies making noises, but the two don't fuse together in the most basic way that any film should. It is for this reason I thoroughly implore anyone going to see WWZ to ensure they see it in 2D - if not to get a stronger perspective of the action, then simply because the 3D isn't very good either.
