What do we expect to see in a films opening title sequence ?

In a good film opening sequence we expect the movie to catch our attention straight away , in order to keep us watching it . It should attract audience straight away.

In Black Swan , a really interesting opening is used which we can definitely say attracts audience by the mystery. A really interesting contrast is used as it shows ballet dancer dancing in white , which we can link that to pureness , however as the video progresses , the music starts to get more dramatic and intense. Blood starts splattering , we can see elements of sinister. The dance is out of focus and the blood and writing is in focus , so the purpose of the whole video is to carry a title, and show the theme of the movie which is a thriller , and elements of sinister.

The second movie with an excellent film opening sequence is Stepfather. The sequence starts with the narrate of the movie. At the start it shows Brad Pitt's name , as this helps the movie to sell a lot as he is a famous actor so many people watch the movie because he is part of the cast. The sequence starts right into the movies plot . The movie is a thriller. The movie uses contrapuntal  sound , as while dead bodies are shown 'silent night' is played which is considered a Christmas carol and a very pure song. So this makes the opening sequence even more creepy. During the beginning of the opening sequence , shaving tools are shown which are organised in a rather very perfect way , which kind of makes the audience think that the man has some sort of OCD , which we can later see that there is dead bodies and that the man is indeed not in his right mind. This opening sequence makes audience question the opening many times , which is very effective at involving audience.
