Since it is a pretty good, and pretty well liked movie, it would be easier for you just to spit out what you think makes it the worst war movie in history.
I’ll take that question...:-)
As a movie, it was just OK, but as history, it was awful.
The setting is wrong, the tanks are wrong, it’s full of small details that are wrong, the events in the film are only barely based on actual events.
Instead of the Americans fighting desperate delaying actions at great cost, the battle was decided by detective work and the Germans running out of gas, or getting run over by it.
It’s a shame that they spent that amount of money and star power on what could have been a tribute to the men who fought and died there. Instead, it was merely a mediocre 60’s action adventure flick loosely based on events that pales compared to other war films of the time like “The Longest Day”.
Factually completely wrong. Tactically completely wrong. Shot in the wrong weather and geography. In point of fact, the movie story line has almost nothing to do with the actual battle of the bulge. Movie ends with Germans abandoning their tanks and walking home, for lack of fuel.
Resembled the actual Battle of the Bulge about as much as an episode of Rat Patrol.
Here’s a lengthy explanation, including why Eisenhower hated it.
