Short credits all the way. Surprised the "20+ seconds" is as high as short credits.
I don't like anims with no credits, it's always interesting seeing how many people went into each one.
But nobody wants..say..credits which are longer than the animation, in which you don't even find out the people's last names.
If you want people to look at your animation, while maintaining good quality, it doesn't make any sense to have huge credits. Put the work into the animation, the part that gets judged, not credits.
Glad I haven't watched the one with credits thats loudness thats power is probably not unlike the apocalypse from X (obligatory cheap joke)
I think the only actual film where the credits are longer is Bambi vs. Godzilla.
In most Hollywood releases, though, the credits are better than the actual film.
But anyway, credits are a waste of time.
