Why is memento a good thriller

i found the opening sequence of memento to really fit the genre of thriller well, The first thing to suggest it is a thriller is the opening credits and the titles. the dark blue writing and black background is a very cliche thing which you see at the start of many thrillers. It also uses extreme close ups and close ups which are used in thrillers, the fact close ups was used increases suspense at make the audience more engrossed in the film.
