Derek Lieu created this mashup of a staggeringly large amount of popular anime shows to show anime opening credits are basically all the same.
An explanation found on Derek's YouTube post:
It's always amused me the repeated imagery that exist in anime opening credit sequences. This video doesn't cover them all, but it has a lot of the big ones. Interesting thing I learned, if a character is running it's overwhelmingly to the left of the screen.
I first started thinking about this years ago when I saw the X-Men intro that they made in Japan to replace the American one. The part that especially hit home was Wolverine, and Cyclops standing on some nondescript land mass.
For this I used only textless credits I found on Youtube (with the exception of Evangelion). So if your favorite anime isn't in here either there was no textless version or it had a pretty unique opening sequence.
Below, a list of all of the anime used in the video:
