A long time ago Roger Ebert wrote a review for the first Resident Evil movie, in which there's a deadly laser trap in a corridor that speeds down at the characters first in individual rays, then in groups of two or so, and finally in an unavoidable mesh that covers the whole corridor, and mentions that this is the first time he's ever seen "a security system with a sense of humor." I thought about that bit while I was fighting the last boss in this game, for which I duly removed a whole star from my rating.
