“I had a convicted stalker stalking me. I had a convicted stalker stalking me. I had a convicted stalker stalking … me.”
An admission that turns from fear to fascination sets the stage for “Baby Reindeer,” Netflix’s darkly comedic psychological thriller based on the experiences of its writer, creator and star, Richard Gadd. The seven-episode series follows Donny (Gadd), a struggling comedian who lives with his ex-girlfriend’s mom and works a dead-end job at a London pub. His life takes a chilling turn when he befriends Martha (Jessica Gunning), a mentally ill woman whose dangerous obsession with him manifests through harassment, assault and a relentless stream of lewd, typo-ridden emails.
