Not that I specifically recall, but I interpreted the comment to mean it was seeing the human(oid) shape that causes the negative feedback. If you can't see the shape... I'm not really sure how it all works. I like the series, but my optimism for its overall quality has dropped a bit. I'll definitely keep watching, but my interest in reading a book that I can't read is growing (and buying the series is less likely). ^^;
