A recent film to have a great credit sequence is “Watchmen,” Zack Snyder’s adaptation of the classic graphic novel.
There was way too much material for the filmmakers to include in the movie version. It was inevitable that many things would need to be left out, thus angering legions of fanboys. But the opening credits do a great job of giving some of the back story in a visually interesting way without bogging down the script with a bunch of extra information.
