The Number 23
I love how simple this is: just a feel of a typewriter, typography and blood splatters. But it also conveys so much tension that gives the audience such an uneasy feeling. The other nice aspect of this is it tells you a bit of the history and story with the added element of infinite varations the integer of 23. The fast cuts, the music, everything just sets you on edge for the movie.
Catch Me If You Can
The unique thing about this title sequence that I like is how it was a handmade design that reflects the time period the movie is set in (1960s). The music also drives home this dated feeling of action and suspense which is nice. The creators of this title sequence really wanted to embody not only the feel of the 60s, but even had the mindset of how they would design this type of animation for a film if they lived in that era. I simply enjoy the simple graphic silhouetted figures and the story they tell.
Fight Club
I love this movie, I love this book. But I also enjoy the title sequence and the idea behind it. We're looking into the fear of Edward Norton's brain, inside the electrical impulses. And every moment we are changing scale, seeing as this fear envelopes every single part of his brain, to even the sweat dripping out of his pores. Then we travel up the reason why he is afraid. And are revealed the whole picture: a gun is in his mouth and he feels as if he is facing death.
Dexter
I really enjoy the setup of his morning 'routine' because it seems to fit perfectly at the beginning of every single episode. I also love the touch of suggested actions of a serial killer added to every single thing he does in his routine: the way its shot and edited helps a lot to suggest these things. All the added emphases on blood also puts you in the mood of how much Dexter Morgan really loves blood. Also, I should note that the music also draws me to this title sequence; it is such an upbeat tone but at the same time so eerie and calculated. It ties together so nicely that its a title sequence you don't really want to skip, it sets the mood of the entire show.
