Well, I can't disagree with your post, at all! The BIEL brain-trust appears to be entrenched in their commitment to not employ advertising, no matter what! So, if I'm permitted to use a weak trope, thus, so what is the McGuffin in this movie scripted by BIEL? To anticipate there's not an answer, forthcoming, to my question, I guess the only fallback we have is to wait and bear witness to the upcoming scenes. That's a wrap!
GLTA!!!
