What are the usual characteristics of Hollywood movies?

Three-point lighting (positive light becomes bright, side light stereoscopic, backlight becomes soft, so that the characters are like a stage, the classic Hollywood period, now advanced machine principle is still the same, but it is not obvious) positive and negative hit the lens and the gaze is consistent (picture corners of a large shoulder or half of the face, the main content is the object) the direction of the lens and the characters move in the same way (seldom to see the lens to the left of the character to the right, the previous shot) Characters from left to right then the next shot must also be from left to right)
