im rating 4 stars because the way the story is amazing, the characters were good at acting and all of the scary emotions were felt from being trapped and not being able to find a way to get out and whatnot, but i genuinely feel it is a 2 star movie BECAUSE I got a panic attack from the movie half way through and i couldn't breathe from all the suspense and claustrophobia i felt! i always watch horror movies but this one just hit different!!!!
