This review is not so much a spoiler, but it points out just how awful people can be to each other when under pressure. It really did remind me of Lord of the Flies in many ways because things went tits up quick, fast, and in a hurry. Considering the events took place over a little more than ten days, the characters didn't take long to show their true colors and true hearts. I was surprised that the island they were on had very little edible vegetation or natural water sources. I was also surprised that there were no organized search parties to explore the island to see what resources were potentially available to the group. I found the movie predictable, but entertaining. I didn't learn any life lessons or was left with a "feel good" feeling, but it did keep me interested for the duration.
