This is by far the poorest element of the whole game and what ultimately lets it down. There is simply no logic to it. The major characters are superbly rendered and bear more than a passing resemblance to the film actors. Extras in the game are less detailed, but, hey, most of them serve as fodder for your de-atomiser, so we don't have to worry too much about that. Rather than use a 3D scrolling world, MIB elects for a static camera, cutting rapidly between scenes as you wander through the game.
Lighting effects are superb.
Most of the time, this approach works excellently, and really does create a good atmosphere. Sometimes, however, it stinks to high heaven. Sure it looks good, but when your character appears about 3mm high it is difficult to work out what is going on down there. The worst example of this kind of thing I found was in mission two when you must traverse levitating rocks in a mineshaft, and the camera shot is so bad that it is utterly unclear which rocks you have to jump between. There really is no excuse for this sort of thing.
