I LOVE this movie! Because...
They don't make many movies like this one anymore! To me it's a comedy like old Goldie Hawn movies.
Super strong female lead with a girl-nextdoor quality, in a big city, succeeding in her career against all expectations, and a great ending that's not ONLY about her relationship with a guy. The pace is so fast like old comedies, too. No one liners. Very dynamic, and not afraid to bring a lot of characters and hierarchies into the comedy.
Miss movies like this. This is the ONLY movie I like Rachel McAdams in, also. For me personally she's too stressed-out looking for others. But she fits perfectly here!
