I would have liked to give 7.5
It's a very good movie, extremely intense though.
Due to its intensity and twists, I can understand why some viewers rated it much lower.
It's heavy.
However, if you are in the mood for an extremely powerful psychological thriller, then this is a gem !
Important to state that if you are looking for an average thriller, then it's not for you.
This movie is very, very intense.
The ending is brilliant.
Casting is excellent !
Really brilliant actors.
Although some scenes are absolutely gruesome this movie's main focus is on the psychological confrontation between the two protagonists.
