I agree the FT13th series was mostly dire but the whole series made huge money.If adjusted for ticket prices and with other considerations,the later Friday's made about what the Saw sequels are making now,in America that is.But yes Saw is huge worldwide whereas Friday's success (at the cinema) was mainly North America.I guess Saw has the advantage of being thriller/horror attracting a wider fanbase whereas Friday was mainly aimed at teens/horror fans.
