I wish I felt differently about Below Her Mouth. It pains me to extol so many of its virtues yet in the same breadth state I don't think it's all that worthwhile as cinematic entertainment.
Krill and Linder have an understated delivery, common to the mumblecore genre. Although this sometimes works against dramatic momentum, it contrasts nicely with - and ultimately heightens - their intimate moments together.
While "Below Her Mouth" is no doubt some classy-looking porn, it's a pretty lousy movie, because all that sex leaves precious little time to develop character, plot or thematic depth.
As badass as Dallas's leather jacket, Below Her Mouth is not subtle. The title means what you think it does. The perspective of only women telling the story narratively and visually creates a powerful class of film and for that alone it's worth the time.
It's a fittingly ambiguous title for a directionless film, late night fare that will be enjoyed by just as many horny men as horny teenage lesbians. Think of it as equal opportunity erotica.
