Query: Good acting but otherwise a poor movie

A bunch of German soldiers fleeing allied advancement towards the end of WW2 take refuge in a tank bunker. The main premise of the movie is that some horrific evil lies in the tunnels that lie unused beneath the bunker. Despite a promising start and very good acting, you gradually realise there is nothing at the heart of this. What seems to be occurring is largely self-destruction driven by a bad case of the "willies" (no idea how to spell that word). The acting is decent, but is wasted on a poor plot with inadequate atmosphere and ambiguous loose ends all over the place. After finishing the film (a chore in itself) you still feel like the key 15-30 minutes of the movie (the ones that would make it make more sense) are missing. Very poor work.
