Example of a Psychological thriller

Memento directed by Christopher Nolan

Throughout the clip we saw, the main convention which was highly noticeable was the fact that the main character is isolated from the other characters. This is because he has a bad condition of memory loss which alienates him and makes him weak and vulnerable. The main character has a fascination, or obsession with his wife's death, and he is determined to avenge her. Also, the main character has conflict with his own mind due to his memory loss, and this causes repetition of him killing people who h suspects killed his wife, and he won't stop until he finds the real killer. In this film, there is quite a mature cast of characters, this is because the director is common for types of films like this. The plot is non linear which means it is quite difficult to understand because it of the flashback's in nearly every scene, and this can confuse the audience. They probably did this so the audience can relate to the main character's feelings of memory loss, so us as the audience can get a better understanding of what he is like.
