i tot Saw was quite good but I definitely loved Se7en, the way Kevin Spacey's character is played out and how truly he believes in what he does makes him an interesting villain and not just a cardboard-style murderer. Saw had it's main attractions in the gore and the twist, Jigsaw was wronged and he felt ppl didn't appreciate life after what he had been through meanwhile John Doe I felt was doing it for the purpose of practicing what his beliefs were, different motivations for both killers
