Thoughts on opening credits.

Currently, I have a few ideas on what opening I should study, but nothing definite.
I have an idea of doing the opening to Cherrybomb as I think it will work well. It shows the two characters and the setting. The whole movie is a flashback, so it has connections to the ending which I think would be good to analyse. But, I have other options too. I thought of doing the opening to Coraline which shows metal hands creating a doll that looks like a young girl with blue hair, the same as the main character of the movie. The scene is Tim Burton-esque and shows the beginning of the troubles in the movie. I have to keep looking around though as I don't feel totally sure about any of them.
