Opening title sequences, important?

Why are opening title sequences important to the film industry?

Opening title sequences are important to the film industry because these first few minutes of the film are what the viewer sees first. They show you what the producers intentions are and they also give you expectations of the film ahead. These are important because the viewer may base the film on what they see first, so putting in a unsuccessful title sequence may lower the viewers expectations of the film, whereas putting in a very successful title sequence will keep the viewer's interest.
Saul Bass once said, "making a main-title was like making a poster, you're condensing the event into this one concept, this one metaphor, a back-story that needs to be told or a character that needs to be introduced."

I researched on the internet and found a particular site interesting, here. It helped me a lot to understand why opening title sequences are important.
