1. There's always something to be said for a psycho-thriller that delivers interesting characters in a cool setting.
2. The film is not a total loss due to its interesting use of suspense and its tactic of placing suspicion on every character. While it's not one of the best thrillers out there, you could easily do worse.
3. Far from a perfect film, but it is a lot of fun. In the tradition of old-fashioned thrillers, the movie has some nice twists and turns in the plot.
4. A riveting horror-thriller that should do for hiking in Hawaii what Hostel did for backpacking in Slovakia.
5. Twohy's script dares and succeeds in peppering the dialogue with funny insider references to Hollywood scripts and actors.
6. Twohy lets his story's central guessing game play out with patient tautness.
7. A big-reveal thriller with surprises that really do surprise -- and are worth waiting for through an audaciously long buildup.
8. A slight film, slight in its surprises and in its suspense, and yet not totally devoid of either.
9. A cunning, sideways-sneaking genre piece with both the fancy to surprise audiences and the adroit filmmaking to do so
10. It works because it's smart, knows it's smart, announces to us that it's smart - then backs off and lets the suspense and dark comedy mix.

What is a brief summary of the following reviews?
While smarter than the average slasher film, A Perfect Getaway eventually devolves into a standard, predictable, excessively violent thriller.
