my choice....Jurasssic Park
The book was amazing and the film could have been equally awesome, but (speaking from somebody who could pronounce the word Palaeontologist at five) they got everything wrong about the Dinosaurs wrong! Since when was a T-Rex a loveable hero that jumps in at the last minute to kill the raptors, the raptors would've kiled those idiots before they could move! And the Raptors themselves are about five feet tallier than they should be, the Biggest Velociraptor palaeontologists have found came up to your waist, these dudes were not Velociraptors they were more likely Utahraptor or Deinonychus as they were bigger.
The Utah raptor hadn't been discovered but Spielburg asked an expert if it was possible for them to be that big and he said that it was. So they did the film and just after they discovered the utah raptor.

I would have to go with The Patriot, Brave heart and U571

"I know lets have a WW2 story with the Americans saving the day.Lets say they capture the enigma code and therefore help end the war quickly. Although it was only the Royal navy that captured them
It looks really stupid at the end when they mention all the people who captured it and it is all RN
