I didn’t find Seventh Sea confusing at all. But it’s certainly more complex and not the entertaining ride Seven is. More significantly it is far more depressing than Seven in my eyes. Seven is about evil incarnate but it’s not really applicable to daily life; it’s a serial killer boogeyman movie. (And Fincher has made a better serial killer movie.) The Seventh Seal is about the inevitability of death and pointlessness of life. Far more alarming!!
