both,

i think its both cause there is all the elements of a thriller and ther is a serial killer( actualy there are 2).

in the movie it cinda calls itself a horror. it was probibly going to be more horror than thriller, but turned out the other way.

if you think about it all horror movies are thrillers, and no not all thrillers are horror.

alot of the time they are classified as the same thing buy the general public. so if its scary its a horror and a thriller, but if its just suspensful its only a thriller
