I’ll generally watch a horror-in-German-bunker flick (there have been many) so I decided to give this one a go. I’d read a few reviews, so I had some expectations of this being a slow burner, which it is. I liked how the film began, with a retro feel to the opening credits, hearkening back to the scary movies of decades ago. I didn’t know anyone in the cast, but they made for quite a motley bunch of soldiers, some experienced and some green. The lieutenant was especially chewing his scenery - which worked for his character arc. I thought the music added to the retro-suspenseful mood as well. Others in forums have said this could have really benefitted from a better budget, and I absolutely believe this, as more money could have provided better horror effects all around. The cast did their best to show the ratcheting up of their terror and hysteria, but the movie needed to give them more to react TO, IMO.
