The main problems is that true evil like Horace doesn't die, and after a black magic ritual conducted in his cell before his execution, neither does Horace's spirit, as a result ...after his physical body is executed Horace's spirit continues inflicting his atrocities in a more supernatural fashion, possessing the bodies of still living to hunt down Jonathon. There's a little more to the plot than that but I'll leave a few surprises for the viewer..... Overall its a really cool flick and the attention to detail is pretty good, especially the way that the hosts infected by Horace have the same gimpy leg that Horace does.
It has a similar feel to another Wes Craven movie, "A Nightmare on Elm St" in many regards and I'd say it would appeal to a similar crowd. The movie has a deliciously 80's hard rock / heavy metal soundtrack featuring Megadeth, Iggy Pop, and "The dudes of Wrath" featuring hard rock icons Tommy Lee, Paul Stanley, Rudy Szarzo and Vivian Campbell which provided a huge bonus for an old metal head like myself!
