Unfortunately, as soon as I saw this almost "perfect" relationship between the couple in Seven, I figured she'd be targeted by the killer. The only trick was figuring out how it related to the pattern. The only "twist" for me was who was going to play "Envy". I saw some of the other stuff coming, but it didn't matter, it was perfectly played.
I think Pitt's character was better in Fight Club than in Seven. Not that he played a completely different character, but that basic arrogant persona worked better in that film. He wasn't supposed to be sympathetic in FC, but in Seven I thought we were supposed to connect to him and I never did. I saw Fight Club last night again just to be sure. Yep, I liked it a lot better, but I am closer to calling Fincher one of the great masters of style.
The biblical references were throw away lines, I thought. The real depth is in the conversations between Freeman and Pitt. A lot to mine out there.
