This movie might keep you engaged and on the edge of your seat but most of the things that happen are out of touch with reality. If you are being stalked by a lunatic, the LAST thing any logical person would do is leave their UNLOCKED cell phone in an UNLOCKED car while they go into a gas station. The plot of this movie could not exist without her doing something like that. A car is ramming another car repeatedly in traffic and nobody notices or calls 911? Just not an accurate representation of what could ever really happen if someone were put in that situation
