Experimento en Alcatraz

I was so excited with this unusual and daring scheme, so unpredictable at first sight, but finally spoiled, smashed by a lousy ending. I was very hopeful to watch one more time an Edward L Cahn's gem, afer DESTINATION MURDER, and before GUNS, GIRLS AND GANGSTERS; speak only of crime flicks, movies not supposed to look, like any other ones. Read closely this story and the expectations are at the highest scale. I don't regret to have seen it anyway, but the ending, I repeat, is unfortunately a bit cheesy, run of the mill. That will not prevent this feature to belong to Edward L Cahn's most interesting films anyway.
