Genre Difference, Repetition and Similarity

Films withing the thriller genre can be very different from one another with he content of the actual film. Examples of this are Shutter island and Taken. They both classify as thrillers but they are very different in terms of mise-en-scene as in shutter island it is set in a mental asylum where most of the lighting is dark which gives an eerie atmosphere. In Taken, the mise-en-scene is a modern setting where it is more familiar to an audience.
The characters in shutter island are doctors, mental patients and detectives, where as Taken has more criminals and policeman, so again it is more relatable to most audience as it includes normal everyday people that you come across.
The narrative events of shutter island are that two detectives come to an island to look investigate the a missing patient, and encounters many problems with himself and his unfamiliar surroundings. In Taken the narrative events include and ex-police officer whose daughter gets taken when she is traveling by a group of sex traffickers who he is trying to hunt down to find his daughter and save her.

 These films come under different sub genres within the thriller genre. Shutter island is a psychological thriller and Taken is just a thriller.
They also have a lot in common as they both aim to have the same effects on the audience. A thriller builds suspense, tension and excitement. This gives a high level of suspension to the audience and gives them something to create anticipation and expectation of the events within the film. The characters roles in the films are still similar. In Shutter Island you feel an empathy and trust within the main character and trust him to solve and save the problems encountered. I some sense this is very similar to the main character in Taken. You feel connected and entrusted in the main character and as the conventions of a thriller go, you expect them to succeed even though they are not necessarily to succeed outside of the film world.
