Riri Riza's 'Paranoia' a half-baked thriller that fails to thrill or engage. None of the story's aspects - domestic violence, pandemics, or a variety of puzzles - are ever completely explored, and Riza's directing frequently falls flat. Nirina Zubir and Lukman Sardi's sleek performances provide some exciting moments, while Nicolas Saputra also offers a solid acting performance for a character whose characterization is too restricted.
