"Field of Lost Shoes" is far from perfect. After all, it's obvious that the folks making the film had a rather limited budget. In many scenes which should have featured many hundreds, only a few dozen are used. However, I don't necessarily see this as an awful thing. After all, the Battle of New Market is NOT the sort of thing that Hollywood would ever make a movie about, so of course the film isn't as fancy or has quite the look of a big production. I can look past this to a certain extent and think considering everything, the film actually looks pretty good.
As for the film apart from the low budget, it's okay...not great, but okay. Instead of focusing on the battle like a documentary, the filmmakers chose to include a lot of fictional subplots--some of which worked and some of which seemed a bit anachronistic (such as Southern students who believe in equality and hate slavery--not something you would have likely heard ANYONE say in the South at that time) or which just didn't work (the love story). I see it as a noble attempt and a reasonably good one at that. Worth seeing if you are a Civil War buff or love history. The ending was quite touching as well. Otherwise, there are a few better films about the era, such as "Glory". Hmmm....now that I think about it, there really AREN'T that many good films about the Civil War and this one is about as good as any...and not nearly as long and ponderous as "Gettysburg".
