User: I think I want to see a movie, but I'm not sure about what specifically I want to see.
Assistant: Well, what do you like.
User: Generally, I like comedies. But they have to be smart.
Assistant: OK. What else do you like.
User: I want a good guy or good girl protagonist that everyone likes.
Assistant: Interesting. I'm narrowing the field a bit. Go on.
User: I also would like to see a film under two hours. I just don't have all day, unfortunately.
Assistant: OK. We're starting to take a turn, here. What don't you want to see.
User: Something really stupid.
Assistant: OK. What else?
User: Something with a jackass protagonist. I want to like the star of the film. I want to root for him or her.
Assistant: Hmm. I see. Anything else?
User: No bummers. I don't want to be bummed out. Happy endings, please.
Assistant: I think I may have something. What about "The 40-Year-Old Virgin" starring Steve Carell?
