Vince Vaughn with a good script can be tiresome enough, but without decent writing he very quickly overstays his welcome.
And in this instance he only has himself to blame as the script was written by him and his on-screen sidekick Jon Favreau's (who brought us the much better Swingers).
Here, we have four couples from Middle America -- each, incredibly annoying.
There's Dave (Vince Vaughn), a video-game dealer, and his housewife partner Ronnie (Malin Akerman); Joey (Jon Favreau) and Lucy (Kristen Davis), high-school sweethearts turned loveless with the typical teenage daughter from hell; Jason (Jason Bateman) and Cynthia (Kristen Bell), an oddball couple who have failed to conceive; and recently separated Shane (Faizon Love) who's on the rebound with a much younger twenty-something girlfriend, Trudy (Kali Hawk).
When Jason and Cynthia announce that they're going to divorce, they have one last chance to save their marriage from the rocks -- a stay in a very expensive paradise resort.
Trouble is, they can only afford to go there if they get a bring-your-friends deal, which coincidentally involves bringing along three other couples.
But this is no ordinary luxury getaway place -- it's more like the Island of Dr Moreau with a bit of romance thrown in.
The island's split into two parts -- Eden West, for couples, and Eden East, for singles -- and outlandish relationship therapy and counselling is mandatory if you want to stay.
Cue plenty of bland, unfunny scenes and the inevitable chaos as Trudy escapes to Eden East, and she is followed across the border with predictable (but dull) results.
Complete with a standard, saccharine-enriched ending, it's a movie that doesn't work as a date flick or an attempt at comedy.
