Water flows like molasses on the nanoscale

Ok, when a liquid flows over a solid, an interface "liquid" layer is always expected to keep sticked to the solid, so that the real flow is not at the liquid-solid interface but at the liquid- "liquid-sticked-to-solid" interface. Hence, it is quite reasonable that if the dimensions of the liquid in the direction perpendicular to the solid surface are reduced up to the molecular scale length, only (a) molecular layer(s) of the liquid sticked to the solid surface remains....but can a molecula-sized layer be considered a liquid?
