Plague Town caught my attention because I'm a sucker for horror flicks that have creepy children in it - to my mind they are the scariest kind.
It started off good, with a few glitches though - some strange scenes that were apparently supposed to build up the tension, but failed at it. The relationship between the two sisters was exaggerated, I thought, and the whole family unit dysfunctional - even so much that I was wondering why on earth would they gone on this trip together.
This being said, the children were creepy enough, although the effect didn't really last. The events in the cottage and with the townspeople were much more effective, while the children took the unwilling role of backscatter.
I won't even start questioning the logic behind the plot - the so-called plague, isolation, unexplained murderous desires and whatnot - let's leave it at that and take the film for what it is.
To sum up, it'll give you a few good scares with a few laughs, but not much more.
