I'm old and out of touch.
All of my examples of great chemistry between two characters (I'm discussing character development and how it impacts romantic chemistry) are SO dated.
Elizabeth Bennett and Mr. Darcy.
Rhett and Scarlett.
Buffy and Angel.
BTW, don't get me started on Joss Whedon and romantic endings, and I'm discussing Twilight in the love triangle portion, so that's covered.
So, I'm asking you to help me out. Who are some of the more recent couples from books, films, TV, etc., who really seemed to connect on a deeper level for you? The example doesn't need to be from the last month or so, but it'd really help if I had a few that are more recent than Buffy.
