The film comes down to the raw basic of film making as it tells a very suspenseful story of three environmentalist about to become Eco terrorist.
The movie's best quality is that it's real low key. They don't try to hide the purpose of the movie or why they are doing anything. They keep this artistic freedom to a low,so the movie is not frustrating or hard to follow.
Which is good because this movie is painfully slow. No real action is in the movie. All the best action is done off camera so you just have to imagine what's going on, which is not hard cause the focus of the movie is clear.
I myself found the movie enjoyable, but I will admit there a lot of slow parts that I almost fell asleep on.
