And as evidenced by yesterday's capture/quote, Barn's crotch wasn't the only crotch of interest in the film:
1972 - Barnabas: 'Well, then, I suppose strictly in the name
of her honor, I must now defile your most intimate and
womanly segments. But then, both Barn's and Angelique's crotches had heavily implied interest in the original series, so it's only right that they should be majorly featured in this film to make sure the points got across for much of today's audience, who, less face it, isn't necessarily as quick to pick up such things if it's simply implied.
They need it handed to them directly.
