This B-Grade movie is loaded with numerous factual errors and goofs. Rank insignia wrong, wrong uniforms and boots, office and household items that post date WW2, filmed in an obvious American submarine that is supposed to be German and on it goes.
This movie was actually available on-line in full HD, to be viewed on 3rd party streaming site about a week before the official release date. I watched it there and waited until IMBD unlocked the "movie review" link after the release date officially passed.
In all honesty, my viewpoint is that any movie with Dolph Lundgren made since appearing in Rocky, is rarely watchable. He has virtually no acting ability at all in my opinion. If I see Dolph Lundgren appearing in the credits of a movie, I am more likely not to watch it, since I find almost every movie with his appearances to be nothing short of disappointing.
As far as the movie goes, the storyline is believable, even though historically inaccurate. It is correct that Germany experimented with rockets launched from submarines with the intended target to be USA, German technology failed to make such a concept operational. Just google "rocket U-boot" to read about the failed program.
There is one scene that left me cringing.... Dolf Lundgren as a Submarine Captain Hans Kessler is inspecting his crew in a building basement. He says, "these are not kriegsmarine", to which the mariners all lined up in different uniforms, and some not even in uniforms (contrary to strict German regulations), start stamping their feet singing a German naval song, which is an attempt to "carbon copy" the same sequence in WW2 classic "Battle of the Bulge" with the tankers singing Panzerlied. Apart from the naval song not being inspirational to anyone not familiar to it, some of the mariners (actors) are seen with their hands in their pockets and not even singing along, not withstanding that it was sung very badly and out of tune.
Like I said earlier, the story line is believable, but as it nears the end, the story line goes off on an unbelievable tangent.
Overall, the movie is OK to watch if you are bored, but it depicts nothing accurate, nothing historical, nothing suspenseful, bad acting, bad cinemaphotography, I consider the movie as a recommendation to watch, only if your lawn grass stops growing and there is no other more exciting action to watch.
I will not say that the movie is a piece of Krap, but it may well be a significant contributor to that pile of Krap you will see popping up on the sidewalk.
