Summary
Deathwatch, brings to the screen the story of a small group of British soldiers who capture a German trench during WWI, only to find out that it is haunted.
The major setback is in relation to some of the acting and some of the dialogues e.g. Andy Sarkis' character is just too much (he is a psychopath); it is indeed very hard to believe that one would find such characters and such lack of discipline in the British army of that time. Yes it is war, yes it is the horrible war of the trenches, but still the British very rarely had to deal with such breakdowns in the chain of command as other armies have often faced. Nevertheless, it is not supposed to be a true story, but fiction, so no argument there.
Aside from that, the story is definitely original, and as for the setting it is excellent. In addition, it does a very good job of being scary!
The film combines horror, drama, action, and adventure making it rather enjoyable, as long as you're in that kind of a mood.
