There are a lot (and I mean a lot) of elements of Just Go With It that don't make sense. Why is Palmer (Brooklyn Decker) completely smitten with Danny (Adam Sandler) when they seem to have no chemistry at all? Why do so many characters use fake accents? And most importantly, when did Dave Matthews become an actor? It's possible to keep yourself distracted during the length of the film simply by adding up the absurdities, but you'll have a much better time if you take a cue from the film's title and don't ask questions. Just go with it.
Danny serves as the film's narrator and central focus, a plastic surgeon who was scarred by love when his fiancée broke his heart. After an accidental twist of fate, Danny learns that he can score many a one-night stand by flashing a wedding band and playing the role of abused husband. He chalks up his behavior to protecting himself from getting hurt again, but changes his tune when he meets Palmer, a 23-year-old teacher with the body of a bikini model (literally) and a good heart. After one night on the beach, the two decide that their relationship could be something real — that is, until Palmer finds Danny's fake wedding ring and demands to meet his "soon-to-be-ex-wife." Unwilling to give up on a woman he's actually falling for, Danny turns to the only woman he trusts, his assistant Katherine (Jennifer Aniston), to play the role.
To find out what makes the film worth seeing, just
The film's far-fetched premise doesn't even end there: Katherine's two children (Bailee Madison and Griffin Gluck) get roped into the production, and seize the opportunity to get attention (along with a slew of other demands). The cute kids provide decent comic relief, but the constant shenanigans they're forced to endure (particularly when Danny scolds Michael for breaking character) sometimes borders on abuse.
The film's jokes can best be described as hit-or-miss; Sandler pulls out everything in his bag of tricks from silly voices to potty humor, but there are as many clunkers as there are laughs. The same can be said for the cameos and supporting players, which range from Heidi Montag to Nicole Kidman. Kidman actually shines as Katherine's snotty college arch nemesis, if only for the fact that it's entertaining to see her in a comedy. On the other hand, Nick Swardson is mostly irritating as Danny's cousin who inserts himself into the charade as Katherine's stuffy "lover."
Romantic comedies are dependent on the chemistry between the two leads, and in the case of Just Go With It, Aniston and Sandler hold it all together. The best friends who don't know they're in love with each other theme is one we're all familiar with, but Aniston and Sandler bring enough charm to Katherine and Danny to make them a couple worth rooting for. Their banter works both on a brother-sister level and on a romantic level, and it's a welcome relief from Danny's relationship with Palmer, which mostly consists of Sandler making jokes about their age difference that feel more creepy than sweet.
Like I said, realism is seldom found in Just Go With It, but there's a beating heart underneath the schlocky plastic surgery jokes and gratuitous shots of Brooklyn Decker's cleavage. Manage your expectations; take the film for what it is, and just go along for the ride.
