I feel like some of that comes down to... Well, us, the adults. For some ungodly reason, we've been calling it things like "a love story" and "a tragedy," and now people just don't know what to expect.
We've also somewhat sanitized it. The pop-culture focus on it tends to be the lengths they go to in order to be together, or the families coming together at the end; but we tend to ignore that the couple is just trying to be together to bone, it's full of dick jokes, and at the end they basically get cockblocked so hard that they die.
Actually, now that I think of it, Kenneth Branaugh is great and all, but I'd love to see a Seth Rogen adaptation of this one.
Looking at the lines on the inside, maybe duct tape? If it gets hot, it tends to leave adhesive behind; and cleaning that up with the wrong solvent can strip the finish off of your floors.
