The Monkey has no pace, no rising sense of urgency or suspense, no real path it’s following and little or nothing that amounts to a message.

Roger Moore

Movie Nation

The Monkey is a blood-soaked barrel of laughs and grisly kills that never finds an effective way to reconcile either of those.

It may not feel as polished or suspenseful as Longlegs, but you can tell Perkins is having a whale of a time putting his years of horror filmmaking to the maximum.
