YMMV / Inchon

• Anvilicious:
  • The Unification Church did its best to force the religious message in the story as hard as it could. Their message is hammered further at the end when Douglas MacArthur is seen preparing for "his most important speech yet," which turns out to be the Lord's Prayer!
  • Similarly, the unsubtle "North Korea=bad, South Korea=good" message, painting the communist North Koreans as mass-murdering monsters and capitalist South Koreans as virtuous fighters or screaming victims. While there's plenty of truth to the former characterization, the contrast would have been more ambiguous at the time than today, as South Korea was still ruled by a military dictatorship during the film's production, and was involved in several unsavory episodes during the war such as the Bodo League massacre. In particular, the Hangang Bridge bombing in real life was done by the South Korean forces without notifying the refugees attempting to cross, resulting in hundreds of avoidable deaths, while in the film, the event is depicted as a necessary final stand against rushing North Korean forces. That said, Reverend Moon wasn't a big fan of democracy, so he probably didn't care.
• Audience-Alienating Premise: The Unification Church was extremely unpopular and widely viewed as a cult in the '70s and early '80s, though their reputation has improved a bit since then. Selling people on a propaganda vehicle for the Church would have been an uphill battle no matter the quality.
• Awesome Music: The makers wanted John Williams, but he chose to not get involved; Jerry Goldsmith's score is much better thought of than the movie and, unlike the movie itself, has had official releases. What makes it more notable is that this isn't the first film about MacArthur he scored; he previously scored 1977's MacArthur with Gregory Peck in the role.
• Questionable Casting: Few critics had anything nice to say about Laurence Olivier's portrayal of MacArthur; besides playing in Large Ham mode throughout (admittedly, not an inappropriate choice for MacArthur), he neither resembles nor sounds like the General in any way, topped by a hideous makeup job that makes him appear mummified. His casting is even stranger if you're aware of MacArthur's contentious relationship with the British military during World War II. Plus, the film ends with footage of the real guy that makes the difference even more obvious.
• Special Effect Failure: There are many instances of badly done SFX, such as greenscreened explosions, obvious fake-looking props, and paper cutouts of planes hanging from a thread over footage.
• They Wasted a Perfectly Good Character: Park, the South Korean man who is arrested along with his brand new wife, forced to kill his fellow countrymen, and then escapes and goes after some sweet revenge. This guy easily could hold down an entire movie on his own, but here he's just a minor figure who doesn't even get a full name, and is randomly killed toward the end.
• Unintentional Uncanny Valley: Olivier is given a downright hideous makeup job to play MacArthur. Not only does he not look anything like the actual MacArthur, more closely resembling Bob Newhart, it looks as though he's been embalmed or mummified.
