At times the 3D effect was pronounced, such as when the camera took in the computer screens at the base, or when when Jake and Naytiri examine the skeleton in Chapter 17. We also appreciated the increased depth of field in some long shots, like the hallway in Chapter 3. At other times the 3D effect was minor or essentially nonexistent, such as when Jake wheels through the lab to meet see the avatar on the tank. We also noticed that sometimes the system would pick certain objects to push unnaturally into the foreground, like the edge of a desk in Chapter 4. This inconsistency became annoying, and we found ourselves yearning for the fixed perspective of 2D fairly quickly.
