Eli tries to mix body horror, medical paranoia, and haunted-house scares before pulling a sharp left turn into demonic thriller territory. It spends its first two acts building a slow, sterile sense of dread inside a vintage medical facility, which works well enough until the plot starts tripping over its own secrets.

While the late-stage genre twist gives the ending some crazy energy, the journey there relies heavily on cheap jump scares and cruel gaslighting. Between the gruesome medical needles and dark religious themes, it is not something for younger kids or anyone squeamish about hospitals. For older teens looking for a goofy horror flick on Netflix, it passes the time, but nobody is going to call it a classic.
