Hike up the tension on paradise island

Whodunnits are usually best served up with plenty of characters and red herrings to keep you guessing until the end. A Perfect Getaway has only a handful of characters (I'm even including the blink-and-you'll-miss-them extras here, too), so there's a danger of it being a no-brainer.

Chances are you'll identify the murderers before the end, but it's a nice ride along all the same.

It opens with cheesy video footage from a wedding celebration as the newlyweds get set to head to Hawaii. Cut to happy couple Cliff (Steve Zahn) and Cydney (Milla Jovovich) living it up in a remote but beautiful part of Hawaii and deciding to hike to an isolated beach.

But there's trouble in paradise with news that another newlywed couple have been butchered on a neighbouring island.

Then Cliff and Cydney have a tense run-in with hitchhikers Cleo (Marley Shelton) and Kale (Chris Hemsworth), two crusty hippies who are anything but chilled. And they're so creepy they've got "we're the serial killers" written on their foreheads. Well not literally, but close enough.

One odd couple should be enough for any honeymoon, but later Cliff and Cydney hook up with battle-scarred former GI Nick (Timothy Olyphant) and his hillbillyish girlfriend, Gina (Kiele Sanchez). Nick is nuts, with plenty of larger-than-life stories. He's handy with a knife, too, and deadly in combat.

Without giving anything else away, the plot's a bit muddled, it's got more red herrings than most movies but it does have those awkward moments when you know your travelling companions are nuts but haven't the gall to tell them to their faces.

An amusing romp with twists and turns that climaxes in a nice blood and guts showdown.

DVD extras: The worst crime in this movie? The lack of interesting additional material, bar a decent director's cut which makes the movie 10 minutes longer as well as the original theatrical cut.
