"Deadpool" may have lost its crown as the top-grossing film of 2016 in the North American box office, but the Blu-ray release has added a couple of noteworthy features to its cap.

Not only is the Ryan Reynolds superhero film the bestseller in Amazon.com's "action & adventure" category -- as you might expect -- it also tops the retail giant's romance chart.

Yes, you read that correctly: The "Deadpool" Blu-ray has crowded out the likes of "Pride and Prejudice and Zombies," "Purple Rain," "The Danish Girl" and "My Big Fat Greek Wedding 2."

It's difficult to say what criteria Amazon's employees use to categorize films, but clearly someone was able to look past the violence, profanity and dirty jokes to see identify the heart of "Deadpool": the relationship between Wade Wilson (Reynolds) and Vanessa Carlysle (Morena Baccarin).

Or maybe they simply saw the film's Valentine's Day banner, billboard and that cheeky TV spot. Or heard Deadpool say, "some of the best love stories start with a murder."

Whatever the case, there "Deadpool" is on Amazon's romance chart, just as a disbelieving Reddit user discovered.

Love is blind, after all.
