Unexpected Appeal to the Unknown

Rating: 10/10 (20 October 2019)

This will be down voted because of the high rating. I know this from reading legitimate "helpful" reviews that are heavily down voted.
I do not particularly like horror movies. At least not the blood and gore kind which might be what the negative reviewers were looking for. I DO enjoy suspense/mystery movies. That's what I felt this movie was (with just a touch of gore). It is the unknown I found fascinating. It had extremely tense moments and extremely moving moments, and I was drawn-in the entire movie. I didn't pick up my phone as a distraction at all. I don't know that I've ever done that watching a movie at home. It's THAT good! Sandra Bullock was superb! The edge-of-your-seat action took me back to her performance in Speed. These are the movies she's made for!
I had very little knowledge of the movie as I don't tend to follow the masses or pay much attention to social media. I knew the basic premise about needing to be blindfolded throughout the movie and that was about it. But, it truly tells a story (with a ridiculous concept) that keeps you intrigued. While watching, I completely forgot how ridiculous it was. I was pulled into the movie, feeling the emotions the cast felt. There's a "Sophie's Choice" moment on the river that I could not help but cry. I was concerned about the ending based on a few reviews I read beforehand, but I was not disappointed at all.
This is simply a must watch for the "average" moviegoer!
