It's a shame that this movie was bad. It had so much potential, only to fall flat on its face. I love John Krasinski, I love George Clooney (both as an actor and as a director), and I love the screwball comedies of the 1930's and 1940's that this film paid homage to. But it was just so much worse than what I've seen before from all three. Krasinki was inappropriately cast in a role he didn't fit into, a role that was ridiculously one-dimensional to boot. Clooney's direction was uninspired and generic; he brought nothing new or interesting to the piece. And the movie just wasn't that funny. It was way too long and drawn out and carried with it almost none of the rapid-fire witty banter that characterizes the older films. The pacing was atrociously slow--with many unnecessary scenes left in--while bad jokes were emphasized and lingered on.
On the positive side, there were some very funny, clever moments. Unfortunately, they were fewer and farther between than the kind of crappy comedies from the late 1990's and early 2000's that I hate (you know, the ones starring Will Ferrell, Ben Stiller, and Adam Sandler). One delightful surprise was Renée Zellweger; I am far from a fan of hers, but she pulled off her role perfectly. All in all, this movie goes highly unrecommended by me. I can't imagine anyone who might truly enjoy this movie, except maybe the cohort of John Krasinski's adoring base of fangirls who will sit through anything he's in.IMDb link: http://www.imdb.com/title/tt0379865/
