There are a couple of thrillers which are my personal favourites. For me, a thriller must have a lot of tension throughout the film whilst it also being very unpredictable. In order for me to regard a thriller as good there should also be a good amount of action in it.
Split (2017)
Split is a 2016 American psychological-thriller film written and directed by M. Night Shyamalan. Casey Cooke is an emotionally-withdrawn teenager, having been molested as a young child by her uncle John, who became her legal guardian after her father's death. While hanging out with her classmates Claire and Marcia, the three are kidnapped by Kevin Wendell Crumb, a man suffering from dissociative identity disorder. Kevin has been evaluated by psychiatrist Dr. Karen Fletcher, who discovered he formed multiple personalities as a means to cope with abuse from his obsessive-compulsive mother.
Green street hooligans (2005)
Matt Buckner (Elijah Wood), a journalism major, is expelled from Harvard University after cocaine is discovered in his room. However, the cocaine belongs to Jeremy Van Holden (Terence Jay), his roommate. Buckner is afraid to speak up because the Van Holdens are a powerful family, and Jeremy offers him $10,000 for taking the fall. Matt doesn't initially accept the money, but reconsiders and uses the money to visit his sister Shannon (Claire Forlani), her husband Steve Dunham (Marc Warren) and their young son, Ben (James Allison) living in London. There, Matt meets Steve's brother, Pete (Charlie Hunnam), an acerbic and imposing Cockney who leads the local football hooligan firm – Green Street Elite (GSE): a group of football supporters that arranges fights after matches.
Taken (2008)
Retired CIA field agent Bryan Mills (Liam Neeson) attempts to build a closer relationship with his shy daughter, Kim (Maggie Grace), who lives with her mother Lenore (Famke Janssen) and her wealthy stepfather Stuart (Xander Berkeley). While overseeing security at a concert for pop star Sheerah (Holly Valance), Bryan saves her from an armed attacker. Out of gratitude, Sheerah offers to have Kim assessed as a singer. Before Bryan can tell Kim, she asks her father for permission to travel to Paris with her best friend Amanda (Katie Cassidy). He initially refuses, but eventually agrees after Lenore persuades him. At the airport, he learns the girls are actually planning to follow the band U2 during their European tour. Upon arriving at Charles de Gaulle International Airport, Kim and Amanda meet Peter (Nicolas Giraud), a Parisian local whose taxi sharing habits act as a ruse to learn more about them. Kim and Amanda go to Amanda's cousins' apartment, only for Kim to find that the cousins are in Spain. While Kim makes a call to her father, she witnesses Amanda being abducted in the living room. Kim follows her father's instructions to hide in a bedroom and listen closely. After she is dragged out from underneath the bed, Kim yells a description of her abductor. Bryan then hears a person breathing heavily, and suspects that one of the abductors has picked up the phone. Bryan then states that if they release his daughter, he will not go after the kidnappers, but warns them that failure will result in a hunt wherein death is an outcome. A man with an Albanian accent answers "Good luck." Later on, Bryan infiltrates a secret sex slave auction beneath Saint-Clair's manor. As soon as Kim comes up for sale, he forces Abil, an Arab bidder, to purchase her. While making his way out, he is knocked out and chained to a pipe, but he manages to escape and eliminate Saint-Clair's henchmen. Bryan forces Saint-Clair to reveal Kim's whereabouts. The Saint-Clair reveals that she is on a yacht owned by a sheikh named Raman, before Bryan shoots him dead. Bryan gives chase after Raman's yacht, he then boards the yacht and dispatches his guards as well as Abil, who is revealed to be Raman's head of security, who gives Bryan a difficult fight. He eventually kills Abil, then enters Raman's suite, only to find Raman holding Kim at knife-point. Raman attempts to negotiate, but Bryan fatally shoots him in the head the moment he lowers his knife. Kim is reunited with her mother and stepfather. The film ends with Bryan and Kim visiting Sheerah.
