Sadly, I honestly think it's because we're too old. I think it's one of those things that you absolutely have to watch at exactly the right age to become obsessed with. (For me, it was Grease 2 at 14, which I still adore despite knowing how very not good it is.) Also, the chemistry between the two leads was ridiculously good, which kept my attention longer than it really should have.

The siblings are, however, creepy. Oh yes. :)
