Identity: begins as a well made but fairly straight forward slasher flick but then morphs into a mindbending psychological thriller and the ending was both heartbreaking and chilling!

Open Water

Suspect Zero: IMO, this is much better than being just merely a seven ripoff it's frequently accused of being!

Joy Ride: The whole movie is great, but it's the climax that especially had me on the edge of my seat!

Frailty and The Mothman Prophecies

Yes, I know that is over 5 but I didn't want to leave any of them out!
