Confessional on shudder is a waste of time!! Not gonna lie, I was on board when the movie first started.  It was intriguing, mysterious and had y0u guessing, but by the end of the movie I found myself asking “who the hell cares?!”
The characters aren’t believable, the acting, while fine, was so over the top it was mind numbing.  What could have been an interesting “whodunit” fell flat on its ass.  Avoid like the plague.
