If "A Perfect Getaway" was named "A Perfect Disaster", perhaps I would have liked it better because I would have known what I was getting myself into. Not only do you have the bad acting of Timothy Olyphant (I think we can all get over the fact he did justice to his character on "Deadwood" and acknowledge he needs to open his damn mouth when he speaks instead of the constant talking through his teeth!), but the plot twist is insanely lame and able to be seen from a mile away. I actually was hoping that the obvious plot twist hinted at the beginning of the film would turn into something else, but it didn't.
In fact I would have been satisfied with two hours of nothing but shots of beautiful Hawaii and it's islands. Seriously, some breath-taking shots in this movie, but that's doesn't help it's piss poor plot and acting. In fact, for those that don't get the plot twist (or shake there head at disgust that it actually goes that route, like I did), they take a nice fifteen minutes and explain the entire plot twist, making anyone who didn't guess the twist feel like a complete idiot, while those who guessed it get to stare at a wall or something because they are so bored for the entirety of that fifteen minute needless explanation. In fact the end has a giant plot hole and a very cheesy but happy ending.
