I think every partnership should have at least one or two guilty pleasures that you share, whether it be a shared favourite old school game, a particular TV show that you simply MUST watch, or a movie that reduces you both to tears. To have nothing in common to enjoy together seems like a pretty boring life together.
And the flip side: you have to have separate interests, as well, otherwise you won't feel like your own person with your own thoughts and ideas. It's healthy to have differing opinions about topics, and it ensures that you've always got something to discuss.
You can be attracted to a person in all physical aspects, but if you can't engage with them mentally then it's only half a relationship.
As to whether the video is based 100% on a true story ... yeah, I remain undecided. I hope it's only a parody; these days, you can never be too sure.
