Jus' sayin'.

Obviously, a variety of characters from all of the houses had tremendous roles in the series. Sure, Rowena Ravenclaw helped Harry and his friends find one of the last Horcruxes, but this doesn't discredit the significance that Hufflepuff students had on the series. While the Hufflepuff house wasn't the star of the show for the entire series, Diggory brought forth a lot of significance to the story in his death and in how he treated Harry. And, according to the Battle of Hogwarts page, when Harry was threatened by the Slytherin house, the loyal Hufflepuffs were right there beside the chivalrous Gryffindors and witty Ravenclaws to fight for what's right. They did not have to be in every scene of every movie and book to have significance. If anything, this last scene has a deeper definition; it shows that the perceived underdogs can help make all of the difference.

Just because a house does not have the flashy appeal of bravery, intelligence or ambition does not mean that the house is any worse. The best type of friend you can have is a friend that is loyal, honest and dependable, after all. And really, speaking from firsthand experience, a Hufflepuff is the best friend that I could ever ask for. The simple things in life - loyalty to loved ones, honesty and a warm heart - go farther in peoples' hearts than bravery, intelligence or cunning could ever, because those are the traits that make humanity, well, human.
