Something Borrowed is a trite romantic comedy about a love triangle on the eve of a wedding (thus the stupid title). The main character is Rachel (Goodwin). Rachel has been best friends with Darcy (Hudson) since childhood. In law school, she met Dex (Egglesfield). And though they like each other, they are too shy to pursue the other's affection. Instead, Darcy's outgoing personality and Dex's openness leads to the two getting engaged.
As for the film itself, nearly every aspect is middle-of-the-road. It's predictably written (including its dumb ending) and appropriately funny. The technical aspects, from cinematography to editing, are completely unremarkable. However, there is one gem in the rough, and that gem is John Krasinski. He epitomizes humor. He is full of wit and sass, mixed in with genuine emotion and heart. I wish he were real and I wish he were my friend. For any Krasinski fan, Something Borrowed is a must-watch. As good as he is, though, he's not good enough to make up for the rest of this movie. If you're not interested in this movie already (and you're not interested in Krasinski), this movie will be an absolute waste of time.
