Malevolent ticks all the boxes of what I look for in a long-form horror story: great pacing, fascinating characters, a high-stakes mystery to unravel, and editing that could make me actually believe a monster from another dimension is manifesting inside of my room. Add to that a brilliant framing device that embraces the audio medium and the fact that this is somehow, impossibly, a one-man show, and you have a breath of fresh air for fans of audio-horror. Well played, Mr. Guthrie.
