I am generally more willing to be open minded about rom coms than many, but this was simply not a very good attempt. Its got nothing to do with comparisons with the British original -- have not seen, and doubt I will. It has a whole lot to do with a meandering plot, lack of chemistry between the leads and a godawful performance/character from its supposed male lead (Jimmy Fallon).

Fallon walks onto the screen wearing the clothes and hairdo of a 15 year old and acting a decade younger than that. He's supposed to be a teacher you see, and of course its well known that school districts the world over love to hire individuals less mature than the children they purport to teach. The character is so extremely disturbed and irrational that I have my doubts whether any actor could have made him likable, but old reliables like John Cusack or Adam Sandler might have been able to give it a shot. Not Fallon, who is neither funny, nor an actor, but appears to think he is both. Not once in the entire course of the movie do you either believe Fallon in his role, or believe that there is any way these two people should, or would be together. Near the end of the movie there is a scene where Barrymore (who was cute as usual but could not carry this one alone -- its hard to have a one person romance) tells Fallon that its over, too much has happened, and she's moving on. And rather than feeling bad about the scene, or sorry for Fallon, you are actively cheering her on -- finally she does what she should have done months ago. But of course the plot mechanics won't allow that to be the end of it (an end which actually might have made a statement out of this mess), and instead we get to see the rational career girl throwing it all away to chase after this childish idiot and encourage his delusions. Its of course meant to be gooey and satisfying, but it actually made me more disgusted than anything else.
