It overloaded your senses, and that was exactly what the bland internet was in need of. Times changed and you didn't know. User are still impressed by cool animation. But now they're also looking for information, trying to order something and want it done quickly all at the same time. Then calm down.
Sensory overload is fine, sometimes.
But when you're trying to move information from a screen into someone's head you'll find that a few carefully thought-out animation tweens and some well placed graphics will allow your user to retain more information. That translates into more sales and hits on your site. Putting too many animations on one screen can make a user's experience seem confusing. It's best to choose a few simple animations that you like and use those repeatedly throughout the whole movie. You want your user to feel as though every page is located within the same site.
