The movie tries really, really hard. I give it an A for effort. Unfortunately it just never really comes together. It's hit an interesting concept. A squad of soldiers must hold a bridge during a zombie outbreak. The zombies aren't their only problem. There's also a demonic creature that lives under the bridge that also proves to be a lethal. The movie delivers plenty of action. There are numerous battles between the soldiers and the zombies. There's also a film is also suitably gory. The acting is mediocre to bad, but I can get past that in a movie like this. Ultimately the movie lacks focus. There are several confrontations between the soldiers and a refugee camp in the woods nearby that never really go anywhere. Then there's the beast under the bridge. It's a completely unnecessary addition that never fully develops either.
Overall the movie is a decent watch for zombie fans. We've seen a lot better but we've seen much, much worse.
