The Good:
Although the idea of the story has been done before, it seldom gets old to me. In a lot of ways, it is become a genre all to itself - "Dimensional Breach" genre (including films like Event Horizon and The Mist and nominally films like Pulse).
I like Ray Stevenson as an actor (see Rome).
The Nazi, the perfect villain.
The Bad:
Little character development.
Slow to start.
I would have liked a bit more exposition.
Some predictability.
Overall: Better than a Sci-Fi Original movie, not great though. I enjoyed watching it and enjoyed the idea. If you don't mind one color tone for an entire film, it's fine really. Nice ending too.
