I get that this is a low-budget attempt at depicting a topic that has been very well done in the past (Battle of the Bulge, Band of Brothers). I don't get "why this story"? It didn't add anything to any previous Battle of the Bulge film or insight. The uniforms may have been true to the period, but they were far from true to the battle... not a stain, not a spot on them, it really detracts from the believably of the film. They all look like they just stepped out of the local dry cleaners. The Battle of the Bulge went on for 5 weeks. They slept in fox holes, and endured rain and snow. There was nowhere to get your uniform pressed and cleaned.
The battle scenes were horrendous, people just walking around like nothing is happening even when their being shot at. No one takes cover, no one shows any urgency. Wounds are unrealistic as well, and there is no real "story". The viewer is supposed to assume they know everything about the famous battle. Character buildup was also extremely thin. It's been a week since I saw this movie, and I can't remember a single character's name.
Effects... bad, but no worse than USS Indianapolis. The bigger issue is it seemed like an excuse to rent a few WWII German artillery, and drive it around in the forest. All that could be forgiven if there was any plot or story, but there just wasn't. Seemed like a college film project, at best.
