right in the beginning one of the cases i looked at was, what if one right and one wrong were replaced by two wrongs, and i marked that as a no op because then you'd have two wrongs when these was only one wrong - in other words, brain cramp.
the consequence of instead going with the case that one right and one wrong replace one right and one wrong was that either my left foot or in the name of the father was the missing film and in the name of the father was disqualified, or that either there will be blood or gangs of new york had to go, leaving a hole which i filled with The Age of Innocence (perhaps my favorite Day-Lewis film).
so then when i was still at 4/5, and you gave the clue that all the films had be mentioned, i realized that AOI had to stay. that's when i realized i had goofed up and went back and found the brain cramp. meanwhile i kept up with proper order and it seemed like it was constrained to that in my final list.
i like this game because i keep making mistakes playing it. it seems to me a step or so more subtle than my brain. seems like i need a clue or two every time.
