Query: The leads have no sexual chemistry!

In a movie that is billed as a "sexy, romantic comedy", don't your main characters have to actually be sexy and romantic together? Because I may be alone in this but I thought their chemistry was severely lacking. They are beautiful people but with no spark whatsoever! And Katherine Heigl - Lord I used to love her until I realized she plays the exact same character in every movie! There were a few parts in the movie that made me giggle but mostly it was pretty lame!
