How many times now has a horror franchise been met with not just a sequel but that inevitable spin-off and, in some cases, a prequel?  Admittedly, there is a mixed reaction as to the lasting effect of modern horror versus the horror found in the gritty 70s and slashfest 80s. For a current franchise set on the supernatural, to obtain enough fan base that they ask for more is a worthy feat.
