“Blood Fest” (*1/2 out of four) was a dumb-and-dumber horror movie about a group of none-too-bright teenagers (Zachary Levi, Seychelle Gabrielle, Olivia Grace Applegate, and others) who go to a horror festival operated by a charismatic but demented host (writer-director Owen Egerton) and they soon find themselves being murdered one by one. A few good gory kills are drowned out by stupid writing and characters who you can’t wait to die anyway. Egerton is amusing in the lead role of the festival host.
