This topic from Long and Short Reviews was an interesting one. I don't tend to pay a lot of attention to couples in books, films or TV shows. However, when I thought about it, I did remember some which I had always liked, although whether anyone would agree with me is open to question.
The Amber Spyglass - Baruch and Balthamos. A pair of male angels from His Dark Materials who are a perfectly imperfect couple, balancing Baruch's tender nature with Balthamos's sarcasm.
The Conjuring - Ed and Lorraine Warren. Portrayed by Patrick Wilson and Vera Farmiga, these created a loving relationship that I completely bought into throughout the film as they used their individual skills to hunt ghosts.
Star Trek: Voyager - Seven of Nine and Chakotay. This only cropped up near the end of the series, but it was lovely to watch former Borg Seven of Nine in her first relationship.
And I couldn't finish without mentioning Azure and Liam Wilder from my novel Photograph. Despite their twenty-year age gap these two are perfect for each other in every way.
So who are your favourite book, TV and film couples?
