Markus, the movie is very good. The day you or someone tells me have seen it, I'll tell the big error they did (or two big errors, I daresay). It's a pity, as I think they take great credibility to the plot. The movie deserves to be watched, nevertheless!
Btw... yesterday I watched "Metallica: Through The Never". I finally found a cinema where the time was more "decent": instead of 1.30 a.m., 20.50 p.m. A lot better in my opinion!! Really good movie, but only to Metallica fans. It's a concert (not a whole concert, though), plus a little crazy plot. If you don't like Metallica, the secondary plot won't make you like the movie. If you like Metallica, the concert in 3D and the great views you can have of the concert will make your day!
