Seen this quite a few times as well, I like the aerial shot of the British Squares, the charge of the French Cuirassiers and of course the British turning back the Old Guard at the end.
The main problem with the aerial shot of the squares is that positioned like that they would be firing into each other. Squares were arranged in diamond formation point to point so that they fired across each others front, the cavalry funnelled in between the squares were then caught in a lethal crossfire. But, nitpicking aside, it was still an excellent film.
