You only get one chance at a first impression...unless you change your opening sequence then you have as many chances as you want

Some of my favourite opening sequences...

.

The Killing, a US remake of Danish programme Forbrydelsen (The Crime). Because God knows the Americans can't just watch a programme from a different country. Ignore the fact that there's four, just pay attention to one of them.

.

Game of Thrones, as good as the opening sequence is, it's not even half as good as the programme.

.

The Big Bang Theory. 

.

 How I Met Your Mother, what I like about this is how all the photos used look like photos that you and your friends would actually take on a night out.
