If I had to be entirely real: both. Both are awesome movies in their own right, and I’ll always remember Chamberlain’s charge down the hilltop as much as I’ll remember the charge of the Scot’s Greys.

Aint filled with action but the story behind production is crazy, and it really pushes forward this notion of a man trying to leverage his reputation and charisma to hold onto a fantastical dream in a decisive brutal line battle where he knows subconsciously that he has let down his entire nation, and everything that he has done and worked for has turned to ash.
The portrayal of napoleon at the end shows a man who has lost his soul, and how beyond reason his men have utter faith in him.
