If the new romantic comedy "Just Go With It" feels as old as the hills, don't worry. It's no hallucination induced from the hot Hawaiian sun.

Like most Hollywood movies these days, "Just Go With It" borrows from previous sources, in this case the 1969 movie "Cactus Flower" as well as a Broadway play inspired by a French farce.

But give it a few tweaks, some designer duds and some serious bikini time on the beach in Waikiki for Aniston and this goody-goody romcom is everything fans expect from Hollywood's sweetheart.

It's light. It's cute. It's got Adam Sandler's kooky one-liners and all that sweet goofiness that made Aniston so popular in "Friends."

But try though it may, this predictable tale can't transcend the obvious follies that transpire when a man rejects real love with a grown-up woman for a fling with a sexy girl.

That girl in question is 23-year-old Sports Illustrated Swimsuit model, Brooklyn Decker (aka Mrs. Andy Roddick).

Blessed with a bikini bod that makes Bo Derek in her prime look frumpy, Decker  gives Aniston, 41, and Sandler, 44 plenty to look at in this caper.

But whatever deeper meaning this movie might have conveyed about true love versus true lust is outsized by Decker's miniscule swimsuits.

The film opens as Danny (Sandler), a plastic surgeon, and his assistant Katherine (Aniston) embark on a consultation with a patient with an uncontrollable eyebrow.

The two try not to laugh, but can't help themselves.

Unfortunately, their jokes feel as frozen as an over-Botoxed face.

Aniston saves the day, not by much

On we go, watching commitment-phobic Danny cruise the parties thrown by his rich clients until he spots a stunning math teacher (Decker) walking towards him.

They talk. The walk on the beach. They have sex and wake up madly in love the morning after.

"I've never connected with anyone like this before," Danny tells the gullible beauty, who believes everything this goofball says until she sees a wedding ring on his finger.

This single man wears the ring to attract women. But Danny knows such shallowness will cost him this dream girl.

Considering all the options, Danny does what every compulsive liar with a heart of gold does: he makes up a story about an-ex-wife who cheated on him and gets Katherine to play the part.

He buys everything  it takes to transform his dowdy pal into a hottie worthy of his infantile fantasies.

The two women meet. But Danny's cockamamie scheme careens out of control.

Before you can roll your eyes one more time, Katherine, her two children (Bailee Madison, Griffin Gluck) and Danny's nerdy pal (Nick Swardson) are pulled into this ruse, which lands everyone on the beach in Hawaii.

The scenery is gorgeous and the umbrella drinks look delish. But all that can't keep us from choking on this fluff.

Sandler, as always, jokes around in his college-boy shorts.

Aniston's performance is one of the better things about this movie.

When Katherine realizes that she loves Danny, Aniston's confusion and vulnerability feels real. That should score some points with moviegoers.

Otherwise, "Just Go with It" is nothing more than a bikini contest between Decker and Aniston.

You'll have to sit through this stinker to find out which girl wins.

One star out of four.
