I choose to watch this film while I was in a search for something scary after mistakenly reading that it has won an award at some "Horrorthon" festival. It hasn't won any awards and it most probably won't. It was just screened there, but I'm glad I watched it. It was pretty much exactly what I was looking for. A creepy and scary horror movie.
For a low budget and an unknown cast this was a very good effort. The other reviewer is right to point out that that it is mis-titled, "Plague Town" does not accurately describe the film, but so what! (And just for the other reviewers benefit, I do not believe they are eating corned beef and cabbage sandwiched, I believe they are eating pasties)
It has barely nothing for a storyline but then most horror films don't. A horror film is about setting the scene and then laying on the threat of what is going to happen next. An American family find themselves stranded in the middle of some Irish countryside near a village which they quickly discover, to their misfortune, is populated by demon children. It has hints of "Children of the Corn", a nudge towards "Rosemary's Baby", and I suspect an admiration for the Sadako character from the Japanese "Ring" films.
I watched this movie alone, in my flat, with the lights off, and it was pretty unnerving in places. It's the first film that I've watched in a long time where I've come away feeling slightly nervous to walk around my own flat. I for sure do not want to get stranded in any Irish countryside after watching this.
