He did say that he was limited to a two hour time frame, and he could have done more if he was alloted more time. I don't know why there was an allotted two hour time frame when you have movies like Harry Potter and Lord of the Rings clock in at around three hours. Yes, the arguement is going to be why do we need a longer film, when it was not received well to begin with. May be the battle could have been more involved, may be the plot could have been more developed. He did work on Gladiator which was a good film. I would have liked to see a longer, more tactically involved battle from him. Honestly, I did expect more out of the battle seeing how this was probably going to be the last film. Although, it is very hard to squeeze a book into a movie sometimes without leaving important pieces out that could have explained more...
