Morning Glory (2010)
Chosen by me because I like to go to the cinema a lot. Plus Rachel McAdams is adorable.
Not as horrible as the similar but woman hating Kathryn Heigl vehicle The Ugly Truth (though this dabbles in the career women must have empty lives cliche it's mostly secondary and not nearly as abhorent) the romance angle is in fact pushed to the background to focus on McAdams trying to be good at her job. Unfortunately the film spends so much time setting up a grumpy unusable Harrison Ford, that when the film starts actually getting a pace to it (basically by abusing Matt Malloy as much as possible) it's almost over and the turnaround in fortunes a little too pat and unconvincing.
McAdams exhibits her usual charm, and Ford is intermittently amusing as an old curmudgeon.
If you took out the numerous montage scenes set to forgettable songs the film would probably be about 10 minutes long.
