You know those credits that roll through the beginnings of movies and tv shows? That's what I mean by a Title Sequence. Some people enjoy them, some could really care less. I think the beginning is just as important as the movie. To me, it sets up the initial mood/how you feel.
The picture above is for HBO's show True Blood. This is one of my favorite sequences for TV. Artofthetitle.com says that the creators of this sequence were inspired by a documentary called Searching for the Wrong-Eyed Jesus.
