This movie is a sensible blend of comedy and romance. There's no exaggerations (well, maybe excepting that one weird date) and everything has a sense or realism, including the dialogs.
Ben Stiller plays it straight. Jenna Elfman is an adorable power business woman. Edward Norton complete the trio with a good performance in a slightly lesser role.
There's a nice soundtrack attached to this interesting script with a number of cute twists. You will not be bored, you will definitively be charmed, and have a number of chuckles.
See it, for some simply enjoyable entertainment.
