Resident Evil - Slice & Diced

Great scene from Resident Evil, I think Roger Ebert even liked it. But he does bring up a good point. Here an excerpt from his review in the Chicago Tribune.

"There is one neat effect when characters unwisely venture into a corridor and the door slams shut on them. Then a laser beam passes at head level, decapitating one. Another beam whizzes past at waist level, cutting the second in two while the others duck. A third laser pretends to be high but then switches to low, but the third character outsmarts it by jumping at the last minute. Then the fourth laser turns into a grid that dices its victim into pieces the size of a Big Mac. Since the grid is inescapable, what were the earlier lasers about? Does the corridor have a sense of humor?"
