Although I did like the modernized version of this tale up to a point, there was a point where I didn't think it was as good as it could've been.  To me it felt like Mr. X was definitely NOT going to do anything to them after he didn't kill the wife with the pendulum.  It may have been a good psychological move at the time, but it didn't feel that good to me.  I guess I'd be middle of the road on this one.
