According to comparitech.com, the Wedding Singer is NH's favorite romantic comedy.  Being from New Hampshire, I love that choice because Adam Sandler, who grew up here in the Granite State,  plays the male lead with Drew Barrymore playing the female lead.  Classic soundtrack too, I love it!

Maine's favorite is Bridget Jones Diary, which doesn't really make any sense to me.  It's a British Comedy.  I would have expected something else, but I'm not sure what.  Massachusetts favorite, Say Anything, features the iconic scene with John Cusack holding up the boom box with "In Your Eyes" blaring out and pointed to his loves bedroom window.

My favorite by far is When Harry Met Sally.  New York choose this as their favorite probably because many scenes were shot in the City itself.  I just love it because of the script and the actors.  I am so reminded of lines that I would probably say coming out of Meg Ryan's mouth.  My best friend, now my husband, follows the lines of Billy Crystal perfectly.  The couples they interviewed at the beginning and end of the film absolutely sends it over the edge for me as one of the greatest movies I've ever seen, never mind my favorite romantic comedy.
