This is underrated
In my opinion, this movie doesn't deserve the harsh comments it has been getting on the message boards.
+ The cast was mostly great, and their dialogue felt genuine.
+ The slow, suspenseful build-up was great too. Few movies do that well nowadays.
+ People acted (mostly) rationally, which is unusual for movies like these.
- I was eventually rather frustrated with the group as they kept allowing themselves to be dragged into Jake's nonsense rather than simply packing up and leaving.
Overall, a good flick that deserves a watch.
