“The Purgation” (*1/2 out of four) was a disposable thriller that might make audiences feel in purgation as they’re watching it. In a Midwestern nowheresville town, a young girl (Tiffany Kieu) attempts to confront her past by revising an old asylum and finding out its untold truths and mysteries. By the end of this, you might feel as if you’re locked in an asylum with her. Yet another tired horror thriller that gives you nothing that both “The Shining” and “The Amityville Horror” didn’t do- and do better- nearly 40 years ago.
