“Caged” is a story about solitary confinement. Viewers remain close to the lead character as he experiences life in a Segregated Housing Unit (an S.H.U., which was the original title for the picture), slowly grasping how hope dwindles and insanity increases during a lengthy stay in a concrete box. Co-writer/director Aaron Fjellman eventually reveals his message of concern at the end of the feature, but it’s an extremely hard sit before such clarity is provided. This is 75 minutes of a man brought to his breaking point by a system that desires to hurt him and memories of domestic strife that haunt him. I’m not sure who the target demographic for the film is. It’s competently acted and its mission is understood, but Fjellman doesn’t provide a strong enough reason to make the journey with him, as much of “Caged” seems constructed to satisfy the helmer, not viewers.
