Probably the worst Godzilla film. The pacing of the film is completely thrown off in the American version by tedious and boring sequences they added of news broadcasters describing the events of the film and making innaccurate claims about the monsters. The film also grants King Kong an incredibly stupid ability (absorbing lightning so he can utilize an electric grip) because otherwise he would have been decimated by Godzilla.
King Kong vs. Godzilla: "Godzilla has a brain about this size. He is sheer brute force, while Kong is a thinking animal. His brain is considerably larger, about 10 times the size of this gorilla skull."
Person watching the film: "WTF? If Godzilla's brain was walnut sized, how would the arteries and veins connect?"
