This was an above-average romantic comedy, mainly notable for the unique situation: A "date doctor" finds himself falling for someone and can't quite seem to do as good a job on his own relationship as he does on others. Will Smith and Kevin James are born to play these kind of light comedy roles. And the writing is above-average (very good at the beginning, falls off at the end).
There are no real surprises in the plot, you can see just about everything coming from miles away. But that's OK, it's still fun.
