Go watch the movie without watching any trailers, or finding out how the concept works. That's how I did it, and I think it would make your expectations better.
The first act made me really interested. It had an original style, the concept was great and just unique overall. I think this movie totally delivered in the second and third act and they made the most out of the idea.
The movie was, in my opinion, crazy. It's just constant fear of whatever crazy thing might happen next. If you are expecting messed up horror, set your expectations low, because it's mainly psychological and brain scratching. I seriously needed a hot minute after watching this to process it all. Heck, I'm still not even sure I understood 100%.
The movie itself has great sound and soundtrack, and beautiful lighting that sets the tone perfectly. The acting is honest and good, it makes it all believable, which it really had to be.
Maybe the movie might be too hard to understand for some, which I would totally get. If you want a complicated but thrilling movie, go watch it. I think it was worth the watch.
