Mixed reception: The early trailer of “Ready Player One” excited fans due to it prominently featuring The Iron Giant, a character from a 1999 animated film who hasn’t been seen in any media since his debut film. Many fans were disappointed when, in the later trailers and final film, the character was seen annihilating people in a huge battle. In the original film, the Giant is shown to be a peaceful character who specifically avoids fighting even though people are very frightened by its extraterrestrial origins.
