I wish more movies were made like this. .I'm also glad I didn't watch any previews. I had know idea what this movie was about. I just knew it had Dylan O'Brien and I like his movies. He always does something different. It was PG-13 and on Max so fee movie night. 75% of the movie I had no idea what was going on and how all of the characters came together. It was written very well so it kept your attention. The acting was very well. This movie definitely makes you think and question things and it is brilliant. Reminds me of 90's thriller movies. It's slow but when it all ties together you will be blown away. It ends perfectly..

Who'd thought: no murders, no gore, almost zero profanity, no nudity, no violence and yet still a solid, watchable thriller...

The cinematography is really good, the pacing is just right, the tone of the film is engaging and lulls you in. The only downside is it's slightly complicated. But then it is dealing with the most mind blowing concept known to man. (No spoilers here).

Acting is spot on and it's emotive but never cheesy. Dare I say this film is a ray of light in an ever growing dark world of films nowadays.

I'd highly recommend this as a perfect Thursday/Friday/Saturday cosy thriller.

Now this may not be a great movie but it's definitely a good one. And once all is revealed highly original. I did guess it before ( after a couple of clues ) I knew the whole story but that didn't ruin the good twists toward the end. Two stories run parallel to each other and both get better and better. As many have said the movie starts of slow and uninteresting. During the first half hour my wife kept asking me what the heck the movie is about but after a couple of plot reveals the story tightens and weaves to come together in the end. O'Brian as always does a good job and is helped by an earnest supporting cast. Pacing also picks up in the second half. As aforementioned stick with it and you should enjoy it as much as we did.
