There's no way it will be better than the original movie. I didn't see it in the theater, but my best friend swears that Optimus Prime's demise in the first ten minutes of the film was the first time he was really exposed to death. He started crying right away and asked his "mommy" what happened to Optimus Prime. Why wasn't he moving anymore?!
It was also probably many childrens' first experience with swearing in a cartoon (SPIKE: It isn't even *dented!* Oh ****! What are we gonna do now?), the last movie Orson Welles worked on, and had a bitchin' musical interlude featuring a Weird Al song. Perfection on film, folks.
