As far as RomComs go, this is a pretty good one. It's predictable, obviously, but it seems to be aware of that and works around it rather well. The jokes are pretty good, the acting is standard fare (although Bullock is above average), and all in all it's worth watching for some light and happy entertainment.
In a sentence:
A standard fare RomCom that nonetheless manages to show some originality by successfully toying with its own predictability.
