User: I'm looking for a movie that is exhilarating to watch.
Assistant: Okay, so an exciting movie, maybe like a thriller?
User: Yes, something with a good twist maybe.
Assistant: Perhaps a movie like Memento, Shutter Island or The Sixth Sense would be good?
User: I have seen those movies and that is the type of movie I am looking for. I like psychological thrillers. Something that will shock me.
Assistant: Do you have favorite movie out of the three I listed?
User: I liked Memento the best, but its only great the first time you see it. Well most of these movies are. Something like Memento would be great. I think I sat and stared at the screen for 5 minutes with my jaw dropped when I saw that the firt time.
Assistant: Have you seen a movie called "The Unknown", its listed as being similar to Memento.
User: I have not.
Assistant: The reviews are okay for it, some people seem to have enjoyed it. There is also a movie called "Before I Go To Sleep". It also has okay reviews.
User: I might be interested in Before I Go To Sleep, who is starring in that film?
Assistant: Nicole Kidman, I've found a review that says she had a very strong performance in it.
User: What does the review say?
Assistant: Strong performances keep the viewer guessing as much as our heroine, but the character drama recedes as the thriller element builds, to its detriment.
