In no case is it clearer than when, talking about Lord of the Rings, they call it "some old movie my dad likes". I'm sorry, but teenagers don't view Lord of the Rings as an old movie that only parents like. That's stupid, and just one of many annoying cases where this series fails to be realistic with regards to teenagers.
This episode was just as terrible as most of the other ones. A series with lots of potential has been ruined.
