The Twilight Saga: New Moon is doing gangbusters at the box office. A huge opening weekend – in fact one of the biggest – for a movie and THE biggest for a movie premiering outside the big summer season. Which brings us to a central question: why? Reviewers did not like it. Okay, quality reviews are by no means a prerequisite for success. Is it the vampire premise? Is it the love story? If you are a tween or the parent of one, please chime in.
