This is clearly a low budget indie film, so don't go in expecting Band of Brothers or Saving Private Ryan. Having said that, if you're able to look past a few sparse battlefields, and decent, but not perfect VFX, then you'll find a pretty good movie.
The first 30 minutes or so are a bit slow, but once you're past that and you get into battle scenes and the rhythm of the non-linear the it really starts to pick up. It's also really more of a drama about the effects of PTSD than a straight forward war film. But of course the distributors want to push the action to sell DVDs.
Even with its flaws this was a surprisingly interesting movie to watch. The non-linear structure was well done and different than what you'd find in this genre. And as a film buff, I'd love to know more about the behind the scenes of the production to see how they pulled off what they did on a limited budget.
In conclusion, don't look down on a movie because it didn't have a hundred million dollars. There's serious merit in new voices outside Hollywood.
