Blake Patterson’s review published on Letterboxd:
For a third of The Descent, Neil Marshall executes the drama among friends to create character development, yet the execution is reminiscent of a Freeform soap opera. Despite this flaw, The Descent is a powerful horror film with some of the most intense sequences in a horror movie this century. Even though the character approach could utilize a rewrite, Marshall examines how friendship can transform into betrayal amid violence and evil. The Descent is fearlessly bleak in the way it displays its gory outcomes, yet Marshall never wallows in bleakness to the point of tedium. Like the best horror films, Marshall finds the right balance between too much and little. The Descent is a riveting demonstration of why I would never climb in a cave.
