A murder mystery/conspiracy thriller should consist of many plot twists and cliffhangers, conspiracies should be mysterious and tense, leaving the audience/viewers feeling uneasy and guessing different outcomes of situations. There should be features of cliffhangers leaving the audiences imagination to wander and create different scenarios for different situations. The murderer in the film would usually always have a connection to the protagonist/victim, which usually makes the murderer less suspected when having a connection or personal relationship with the protagonist, this also creates plot twists because the viewers may not expect the murderer to be who it is or they may not expect the protagonist to be the victim. Typically, in a murder mystery film, you don't find out who the murderer is until the very end, which results in a lot of tension and a build up of suspense. There is usually some sort of obsession with the murder to the victim, whether they are a stalker or are jealous, there are always themes of possession over the victim. There are usually different turns of events, leaving the audience shocked and having unexpected outcomes/surprises in the film which wopuld shock the audience because it seemed unlikely to happen.
