What are your Underrated Thrillers?

So I've been writing for Den of Geek again; my latest effort is a list of thrillers I consider underrated. I cheekily slipped in a few well-known titles (why doesn't everyone rave about them more?) but it's largely a list of the low-budget, lesser-known flicks. 

Here's a picture from Burning Bright, because the lovely Briana Evigan favourited the tweet one of my fellow Den of Geek writers sent to inform her of the article. Yay, girl crush!
