This one now tops my chart of the best thriller/ mystery movies of all times! Seriously the best. While watching I didn't feel bored at all just how it happens sometimes during other horror/ thriller movies but this kept my eyes wide open and my heart rate was beating fast throughout the movie. Several plot twists, a fantastic storyline and strong acting with some emotional events made it worth it. You should absolutely go and check this movie out! It's worth it! At first you may feel a bit confused but as the scenes unfold, all the pieces will come together and you'll get to know what's actually happening. Grab some popcorn and a cozy blanket and give this a shot!
