This movie, while not horrible, is obviously low budget. That said, the Saints and Soldiers series do an admirable job of creating realism with excellent props, especially when considering the low budget. The acting, for the most part is campy, preachy, and over the top. A few of the guys do fine jobs, but most could be much better.
But let's be honest, where this movie shines is in getting to watch two beautifully preserved M18 Hellcats and a Pz.III in action. Which brings up one minor gripe; In WWII, armored vehicles were nearly unrecognizable due to the amount of crap they had on them. From backpacks, to wooden ammo and ration crates, to tarps, to sandbag and log armor, etc. These vehicles looked like they just rumbled off the showroom floor.
But all in all, I gave it a 7. For WWII armor buffs, you won't find a better movie out there that features Buick's beautiful tank destroyer, which was well loved by it's crews. For those who like fast, light US armor, also check out The Bridge at Remagen, for some incredibly fun M24 Chaffee action.
