Title design and typography are fantastically subtle art-forms not fully appreciated by the wider public, but which, nevertheless, have a profound impact on their experiences.
I know within about 5 seconds of a title sequence that I'm in either the safe hands of gifted film maker, or a "5 for the price of 10" hack. Never been proved wrong.
I still find the Citizen Kane title card the most startling. Its incredibly aggressive graphical presence says one thing about the movie's character, but the wall of complete silence it appears in says another. Immediately unsettling and intriguing even now... but in 1941? Wow. Brilliant.
