Defining The Decent's genre

The decent is a horror this is obvious as it has many conventions of the horror genre like blood and gore and horrific injury's and deaths however it also has elements of a thriller as the crawlers jump out a lot and scare the audience, also there is lots of tense music used and the lighting is quite dark to emphasise this claustrophobic cave and to allow the idea that crawlers to be anywhere. So The Decent is definatly a hybrid however there is also sub-genre's such as slasher in The Decent as the women kill the crawlers with pick axes they stab and slash them with these weapons so it also has some sub-genres in The Decent.
