Open the Door

A decent Korean thriller that fits the mold of so many similar genre films of late. Home invasion, cybercrime, stalking etc. It doesn't do much to improve the formula, but it will do for a casual watch.

The film minimizes blood and guts, instead playing up the psychological terror that victims suffer from cybercriminals. Our protagonist really does go through considerable distress with hardly any way to protect herself since the elusive villain's methods are scarily effective. He often hides in plain sight, and the screenplay cleverly keeps him hidden until late in the story. Thus we have both a mystery and a stalker thriller that plays its cards straight, with little diversion from the main plot.

It does progress into something more conventional later on, and it might have been more memorable if it strayed from the norm. But we'll have to do with what's presented here, and that's a polished piece of tension building that doesn't do anything to impress, but just about scratches that thriller itch before you move on to something better.
