- No Problem with Licensed Games: Whereas the movie was horribly received, the Famicom tie-in game Ikari no Megaton Punch (which was never released outside of Japan) is actually pretty decent for the time. It's sister game for the MSX2, Yomigaeru Densetsu (also a Japanese-exclusive) was also decent.
- Sequelitis: The previous film was already a sub-standard remake, and this film wasn't an improvement. Unsurprisingly, it was savaged by critics upon its release (USA TODAY's Mike Clark suggested the reason "America's Biggest Hero Is Back...And He Is Not Happy" was that "Dino De Laurentiis showed him the rushes"), and flopped at the box office.
- So Bad, It's Good: The film is less serious than its predecessor, if not outright campy.
Col. Nevitt: We should have no problem identifying the enemy; they're approximately 50 feet tall and wearing their birthday suits.
- Special Effects Failure: The suits, compared to the 1976 film at least, are rather hokey looking and unimpressive. This might have to do with the film's lower budget though ($18 million compared to the '76 film's $24 million). That the film's costumes were made by Carlo Rambaldinote as opposed to Rick Baker might also have been a factor.
- The chroma key effects are just as, if not more, cheap like the costumes. Kong smashing an army man into a grave is a good example.
