OK, Deathwatch, yeah, this is what I was looking for. Thanks, guys.
Cripes, even the official movie site is creepy...
Too bad the article/review that an0n posted says that the "evil force" that kills off those soldiers is never explained. That was the reason I wanted to watch that movie.
"In part, Deathwatch succeeds because it takes a narrative step that some find annoying, some find to be a bit of a bullet dodge. The nature of whatever it is in the trench is never fully explained: hints, ideas, suggestions, theories will be rife, but it remains nameless. Whether it is God or the Devil in that muddy pit is left to the audience."
Yeah, the scariest things are that which cannot be seen, but come on, when the movie is over, we gotta have
some kind of explanation of what happened! How can you end a one-shot movie (meaning this movie is not likely to have a sequel) without a resolution?
If this movie is just about nine Brit soldiers going mad and dying in a German trench and only one guy survives without an explanation of what killed the other eight, then what's the point of watching this movie?

Do many horror movies consistently seem to have no plots or is it just me?

Like the article stated, I find this both a bullet dodge AND annoying.
As to whether it's God or the Devil in that trench, my money is on Big D. War is hell and Hell is the absence of God (or so I'm told). If the trench is a hellhole, then God wouldn't be anywhere near that place.
I never cared much for horror flicks, but I'm really curious about this movie.
